Episode 68


In today's episode (Episode 68), the author continued his explanation of differentiation (remember, the topic was introduced as part of the foundational topics in Program F12 (Episode 42)). In this new program (Program 7, page 544), following the author's exposition, I reviewed derivatives and some standard derivatives, as well as methods of differentiating functions in their various forms. I concluded the video with an explanation of logarithmic functions - an easier method to differentiate more than two functions when the product/quotient rule might be longer to use.

Islam › Despite The Hardship In Nigeria, Please Let's Strive For Halaal Earnings by Lukgaf(op): 12:16pm On Feb 02, 2024
As we navigate the challenges of economic hardship in Nigeria, it is crucial to reflect on the ethical choices we make, especially when it comes to our earnings. Our beloved Prophet Muhammad (peace be upon him) emphasized the significance of halal sustenance, that this life is temporary, and our actions will be accounted for in the eternal Hereafter.

In the face of economic difficulties, the allure of quick, albeit unlawful, gains may be tempting. However, let us be mindful that the temporary relief such earnings provide carries eternal consequences. Allah, in His infinite wisdom, has prohibited certain means of acquiring wealth, and our commitment to halal earnings is a testament to our faith and trust in His divine provisions.

Allah says:

"And do not consume one another's wealth unjustly or send it [in bribery] to the rulers in order that [they might aid] you [to] consume a portion of the wealth of the people in sin, while you know [it is unlawful]." (Quran 2:188)"
In closing, it is important to discern genuine scholars from those who may mislead. There are individuals who, unfortunately, lend an ear to half-backed scholars subtly endorsing unlawful practices.

A genuine scholar, firmly grounded in knowledge, would unequivocally discourage engaging in illicit activities such as 'yahoo yahoo' or any form of dishonest earnings. True scholars are guardians of the ethical and lawful principles outlined in Islam, guiding us toward righteousness, patience, and trust in Allah's mercy during challenging times.

May Allah grant us strength, resilience, and the wisdom to make choices that align with His commandments.
Islam › Means Of Goodness by Lukgaf(op): 11:58am On Feb 02, 2024
This week, let's review the 29th hadith of the forty hadith of An-nawawih. For the past review, see here

"On the authority of Muadh bin Jabal (may Allah be please with him) who said:

I said, 'O Messenger of Allah, tell me of an act which will take me into Paradise and will keep me away from the Hellfire.' He (peace be upon him) said, 'You have asked me about a great matter, yet it is easy for him for whom Allah makes it easy. Worship Allah without associating any partners with Him; establish the prayer; pay the Zakah; fast in Ramadan; and make the pilgrimage to the House.'

"Then he (peace be upon him) said, 'Shall I not guide you towards the means of goodness? Fasting is a shield, charity wipes away sin as water extinguishes fire, and the praying of a man in the depths of the night.' Then he (peace be upon him) recited: '[Those] who forsake their beds, to invoke their Lord in fear and hope, and they spend (charity in Allah's cause) out of what We have bestowed on them. No person knows what is kept hidden for them of joy as a reward for what they used to do' [as-Sajdah, 16-17].

"Then he (peace be upon him) said, 'Shall I not inform you of the head of the matter, its pillar and its peak?' I said, 'Yes, O Messenger of Allah.' He (peace be upon him) said, 'The head of the matter is Islam, its pillar is the prayer and its peak is jihad.' Then he (peace be upon him) said, 'Shall I not tell you of the foundation of all of that?' I said, 'Yes, O Messenger of Allah.' So he took hold of his tongue and said, 'Restrain this.' I said, 'O Prophet of Allah, will we be taken to account for what we say with it?' He (peace be upon him) said, 'May your mother be bereaved of you, O Muadh! Is there anything that throws people into the Hellfire upon their faces, or on their noses, except the harvests of their tongues?'

[Tirmidhi]"


The key points are as follows:

Essentials for Paradise:

- Muadh seeks advice from the Prophet (peace be upon him) on actions leading to Paradise and safeguarding against Hellfire.
- The Prophet's response emphasizes fundamental acts: worshiping Allah alone, establishing prayer, giving Zakah, observing fasting in Ramadan, and performing the pilgrimage.

Means of Goodness:

- The Prophet expands on additional means of goodness: fasting as a shield, charity erasing sins like water extinguishing fire, and night prayer.
- The emphasis on nighttime prayer highlights its significance in drawing near to Allah.

Guidance on the Essence of Islam:

-The Prophet succinctly outlines the essence of Islam: Islam as the head, prayer as its pillar, and jihad as its peak.
- This hierarchy signifies the centrality of submission to Allah, the importance of prayer, and the pinnacle of striving for His cause.

Foundation of All Matters:

-The Prophet identifies the foundation of all these principles by symbolically holding his tongue.
-The restraint of the tongue is emphasized, underscoring the accountability for careless words.

Warning Against Harmful Speech:
-The Prophet illustrates the potential harm of the tongue, emphasizing its role in leading individuals to the Hellfire.
-This serves as a powerful reminder of the consequences of thoughtless speech and the need for mindful communication.

In essence, this hadith imparts comprehensive guidance, urging believers to adhere to the fundamental tenets of Islam, engage in virtuous deeds, and exercise caution in their speech.

The Solution To Nigeria FX Problem

How CBN can tackle raising inflation and bring down usd 1$ back to N200 or N500 at most.

1, For Nigerians travelers ( that needs physical cash BTA)
Asign personnel to Exchange fx directly from the Airport only with requirements like visa and traveling ticket evidence.

2, most of the Exchange fx can as well be gotten from the returning at the airport from those who might want to change their fx.

3. A) all Nigerians that needs foreign currency must open an E-naira accounts. Confiscate and mop up all physical foreign currency trading in the market and issue them the digital currency wallet via the e-naira. They can hoard limited fx if they like but it must be digital on the e-naira wallet and not on the physical notes.

B) Create a dollar, pounds, euro wallet account . (At least the major currency Nigerians are mostly using) inside the E-naira platform where people can conveniently move monies from there enaira account at the approved exchange rate converted to all currency wallets. They can as well convert it back to naira wallet any time as needed.

C) Major importers will have to registered with the CBN and ensure they are truly importers and have their limit increases base on their import capacity. No physical dollar will be giving but digital dollars on their e-naire. Also encourage foreign merchants especially the Chinese to open an enaira wallet for easier transactions. Cbn will need to promote and sell the enaire idea to Chinese merchants.

D) mini importers and others can make purchases online with the enaira dollar mastercards at a minimum limit of 5k or 10k usd a year.

E) flight tickets booking should be done via enaira master cards.

F) school fees or those sending money abroad can use the same enaira cards or crypto currency as it already been done.
Hope criminally minded Nigerians will not game this

Politics › Re: Opinion: On The Effect Of Fuel Subsidy Removal And Floating Of Naira. by Lukgaf(op): 11:09am On Jan 30, 2024
9jatriot:
The simple answer to your novel idea is roundtripping. Collect at a subsidized rate from government and sell at market rate. Officials stealing it.
You see this our Nigerian citizens, we are a peculiar people. People here most play the blame game and complain when they are not the ones of it is not their person benefiting.
But I think if linked with NIN where people thumbprint and they (those in charge) give account based on the number of people (thumbprint) captured, that might reduce round tripping I think.
Politics › Opinion: On The Effect Of Fuel Subsidy Removal And Floating Of Naira. by Lukgaf(op):
Reflecting on the harsh consequences of fuel subsidy removal and the growing high rate of Naira to Dollar, coupled with the government's plan to have proceeds from fuels sold by NNPCL directly remitted to the CBN account instead of NNPCL's personal account, I explored multiple pages of comments on Nairaland where related was posted to gauge public perception of the new policy. See the thread here

Subsequently, I engaged in a discussion with a good brother(a mathematician turned accountant), to gather insights on whether this move might address corruption within NNPCL and earn us more FOREX. In our conversation, we discussed various challenges facing our country. In summary, we agreed that while certain government policies, such as total subsidy removal and a floating Naira, are theoretically sound, their effectiveness is hampered by the complexity of Nigeria and the attitudes of our people.

A few hours after our conversation, an idea surfaced in my mind on how to address the problem of food insufficiency, which disproportionately affects the poor and makes life challenging for civil servants. What if the Federal Government collaborates with private food companies, like Gunju farm Fresh, that sell food bags (e.g., Ramadan packages with 25kg rice, 5kg beans, and other items) for around 60k ?

The government could purchase these items in bulk and sell them back to citizens at a more subsidized rate, say between 30-35k. To prevent corruption, they could incorporate people's National Identification Numbers (NIN) at authorized centers in each local government and provide a thumbprint before purchasing the subsidized food. Each NIN would be entitled to only one bag per month, curbing corruption among those in charge.

In my opinion, this approach appears more effective than the current palliative measures that often fall into the hands of the greedy and corrupt individuals or where are the CNG buses, the rice and billions of Dollars they said they distributed?

Additionally, such an initiative could create job opportunities as food companies would require more personnel thereby reducing the problem of unemployment.

This strategy could be sustained until the subsidy removal regime is over, there is a stable exchange rate, and there is an increase in the new minimum wage. What are your thoughts on these?

Thanks

Is this how to answer simple questions for God's sake? Which one is comes with everything? I already asked twice yet you've not given any proper answer.

What's the name of the app? Simple question and answer. Even if it comes with phone, the app should at least have a name I guess.

Then did you use a Stylus pen? Another simple question requiring a simple answer.
I meant that the Samsung Galaxy s6 lite I told you about comes with everything including the app and the pen you were asking about. There's an inbuilt app called "Samsung note".

So how do you still want me to reply you?

I think brother, you should try and learn how to ask questions politely especially from people you haven't met before. Peace!

If you can tell me the answer to this simple math, I will accurately tell you your birthday. Ready?

- Take the number of the month in which you were born (e.g., 2 if you were born on the 27th day of February).
- Double the number (i.e., 2 x 2 = 4 ).
- Add 5 to it (in this case, 5 + 4 = 9).
- Multiply your result by 5 (i.e., 9 x 5 = 45).
- Put a zero behind your answer (450).
- Add your date of birth (450 + 27 = 477).

By telling me the final answer from your own calculation, I can accurately guess your birthday!

Islam › The Certainty Of Death by Lukgaf(op): 9:27am On Jan 26, 2024
In this transient world, uncertainties surround every aspect of life, except one – death. It is an inevitable reality, a journey we all must embark upon, yet the when, where, and how remain elusive.

Recently, I came across a poignant post on NL detailing the demise of a brother merely two days into his UK study venture. Another account recounted the passing of a fellow brother following a seemingly trivial headache. Such stories serve as a reminder that our turn will come, but the hour is unknown.

So, are we preparing for the inevitable? Are we repenting from our sins? Are we striving to be better individuals each day?

This is a call to evaluate our actions, align them with moral values, and strive to live in a manner that pleases Allah.

Contemplating the certainty of death is not meant to induce fear but rather to inspire a meaningful and purposeful life. It is a call to righteousness, self-reflection, and sincere repentance.

May Allah grant us a good ending (Aameen)
Islam › The Obligation Of Following The Sunnah by Lukgaf(op): 9:12am On Jan 26, 2024
This week, let's review the 27th hadith of the forty hadith of An-nawawih. For the past review, see here

It was narrated on the authority of Abu Najih al-Irbad bin Sariyah (ra) who said:

"The Messenger of Allah (sas) delivered an admonition that made our hearts fearful and our eyes tearful. We said, "O Messenger of Allah, it is as if this were a farewell sermon, so advise us." He said, "I enjoin you to have Taqwa of Allah and that you listen and obey, even if a slave is made a ruler over you. He among you who lives long enough will see many differences. So for you is to observe my Sunnah and the Sunnah of the rightly-principled and rightly-guided successors, holding on to them with your molar teeth. Beware of newly-introduced matters, for every innovation (bid'ah) is an error."

(Abu Dawud & Al-Tirmidhi, who says it is an authentic hadith - hasan saheeh)
This hadith encourages believers to prioritize Taqwa, obedience to authority, adherence to the Sunnah, and caution against innovations. It serves as a timeless guide for navigating challenges within the Muslim community and maintaining a steadfast connection to the teachings of Islam.

Among its lessons include:

1. Importance of Taqwa (Allah-consciousness): The Prophet emphasizes the significance of maintaining Taqwa, fostering a conscious awareness of Allah in all aspects of life.

2. Obedience to Authority: Regardless of the qualities of a ruler, the hadith instructs believers to listen and obey their leaders, emphasizing the importance of stability and order in society.

3. Anticipation of Differences: The Prophet predicts the emergence of conflicts and differences within the Muslim community over time, highlighting the need for steadfastness and adherence to guidance.

4. Adherence to Sunnah: The hadith emphasizes the importance of following the Prophet's Sunnah (traditions) and those of the rightly-guided successors, highlighting their role as a source of guidance for the community.

5. Firm Commitment to Sunnah: The metaphorical expression "holding on to them with your molar teeth" underscores the seriousness and unwavering commitment required in adhering to the Sunnah.

6. Warning Against Innovations: The hadith warns against newly-introduced matters, categorizing them as errors. This emphasizes the need for caution and adherence to established traditions, discouraging the introduction of innovations in religious practices.

Islam › Re: Is Fasting In The Month Of Rajab Recommended? by Lukgaf(op): 8:26am On Jan 19, 2024
The sacred months are: Rajab, Dhu’l-Qa’dah, Dhu’l-Hijjah and al-Muharram.

Al-Bukhari (4662) and Muslim (1679) narrated from Abu Bakrah (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: “The year is twelve months, of which four are sacred: three consecutive months, Dhu’l-Qa’dah, Dhu’l-Hijjah and al-Muharram, and Rajab Mudar which comes between Jumada and Sha’ban.
Islam › Is Fasting In The Month Of Rajab Recommended? by Lukgaf(op): 8:25am On Jan 19, 2024
There is no sound hadith to indicate that there is any special virtue in fasting in Rajab.

What some people do, singling out some days of Rajab for fasting, believing that they are better than others, has no basis in shari’ah.

But there is a report from the Prophet (peace and blessings of Allah be upon him) which indicates that it is mustahabb to fast during the sacred months (and Rajab is one of the sacred months).

The Prophet (peace and blessings of Allah be upon him) said: “Fast some days of the sacred months and not others.” Narrated by Abu Dawud, 2428; classed as da’if by al-Albani in Da’if Abi Dawud.

Even if this hadith were sahih, it indicates that it is mustahabb to fast during the sacred months. So if a person fasts during Rajab because of this, and he also fasts in the other sacred months, there is nothing wrong with that. But singling out Rajab for fasting is not right.

Islam › Steadfastness: Lessons From The Story Of Prophet Musa, His Mother, And Pharaoh by Lukgaf(op): 8:14am On Jan 19, 2024
There are valuable lessons to be gleaned from the story of Prophet Musa, his mother, and Pharaoh as narrated in the Holy Quran. One noteworthy lesson is the importance of steadfastness and patience in the face of Allah's decree.

During Pharaoh's oppressive reign, he ordered the killing of male infants. Despite the cruelty of Pharaoh's regime, Prophet Musa was born at a time when a prophecy foretold the downfall of Pharaoh's kingdom at the hands of a male child. Remarkably, in an act of divine mercy, Allah orchestrated Musa's upbringing under the very ruler who sought to eliminate him.

The Quran narrates, "We inspired Moses's mother, saying, 'Suckle him, and then, when you fear for his safety, throw him in the river: do not be afraid, and do not grieve, for We shall return him to you and make him a messenger" (Surah al-Qasas, verse 7).

This directive may seem puzzling. Musa's mother, despite praying for his safety, was instructed to cast him into the river. However, Allah's plan unfolded perfectly as Musa not only survived but received an upbringing of distinction even in the household of his potential enemy.

As Muslims, we are urged to draw lessons from this narrative. Regardless of our circumstances, gratitude and reliance on Allah should be our guiding principles. Often, we may feel that our prayers go unanswered, but Allah, in His wisdom, responds in ways that are ultimately in our favor. Even in moments when we believe all hope is lost, we must not despair, for Allah knows what is best for us.

As stated in Surat Al-Baqarah (2:216), "But perhaps you hate a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allah knows, while you know not."

May Allah grant us faith, and firmness in our resolve, and may He answer all our prayers.

Inspired from one of the Tafseers of Shayk Dr. Luqman Idris (May Allah be protect him).
