Without doubts, one of the subjects students really find challenging in our schools (from basic to grad schools) is Mathematics. Even though Mathematics is one of the core subjects in our basic and high schools, many students still fail it. For example, about 45 percent of the candidates who sat for the 2021 WASSCE failed Mathematics and about 70 percent in 2020. This is also true for other terminal examinations. Very disheartening! One of the reasons is the way some mathematics topics are being taught in our schools. Another reason is the use of complex terms to explain the concepts. Also, there are inadequate mathematics resources in our schools and the available ones are handled by incompetent mathematics teachers. Some schools have no mathematics teachers at all and thus rely on other subject teachers to teach this "core" subject. Haven't you seen a school where a Yoruba teacher or a teacher with an art and humanities background is being compelled to teach mathematics? This is so unfortunate! So, fellow Nairalanders, while surfing the internet recently, I came across some resources online with hundreds of math videos that students (even those with zero math background) can use to learn this tough subject from scratch with ease. I can vouch that our brothers and sisters (or children) preparing for terminal exams such as WAEC, NECO, JAMB, NABTEB, and even first-year students would find them useful. Below excerpt is the transcript of what the instructor said at the beginning of the videos: "I have taught in many schools across Africa and across different levels (from primary to graduate level). I have informally started teaching mathematics right from my childhood when I taught and assisted my siblings with mathematics home works. I am particularly interested in starting this online class to assist students to clear some misconceptions some students have about mathematics. With the help of God Almighty, I have changed the narrative of many students who had a misconception about Mathematics in the past. I hope through this series you can also clear some of these misconceptions. Before I proceed, let me ask you: do you know can excel in math and have an excellent grade in your math exam? do you know you can become a Guru in math? That is possible! for example, let me ask you a mathematics question: what is 1 + 1 ? Guess, 2? waooh! clap for yourself! Tre tre bien! Mathematics is as simple as that (1+1). So sit down and enjoy learning Math from scratch!" The link to the playlist is: https://www.youtube.com/playlist?list=PLn0ZvdWhZVXcASYpr4SViyKOip5i58mu5 But, I will try as much as possible to post some of the resources here so that people can benefit |

From the image below, can you recognize a white/black race? A male? Female? Who is beautiful/handsome or ugly? Who speaks Yoruba? Hausa? Igbo? President? Rich? Poor? Professor? Students? It doesn't matter your status in society, ethnicity, language you speak, whether you are beautiful or ugly, rather how pious you are. Allah says in Suratul Hujroot verse 13. يَـٰٓأَيُّهَا ٱلنَّاسُ إِنَّا خَلَقْنَـٰكُم مِّن ذَكَرٍ وَأُنثَىٰ وَجَعَلْنَـٰكُمْ شُعُوبًا وَقَبَآئِلَ لِتَعَارَفُوٓا۟ ۚ إِنَّ أَكْرَمَكُمْ عِندَ ٱللَّهِ أَتْقَىٰكُمْ ۚ إِنَّ ٱللَّهَ عَلِيمٌ خَبِيرٌ O mankind, We have created you from a male and a female, and made you into races and tribes, so that you may identify one another. Surely the noblest of you, in Allah’s sight, is the one who is most pious of you. Surely Allah is All-Knowing, All-Aware. Be humble and increase in piety! Photo credit: Ilir Aliji

Do you know Rajab is one of the four sacred months we have in Islam? How about fasting in it? Is fasting recommended? Below from IslamQA, I present some issues concerning the sacred month of Rajab and whether it is recommended to fast some of its days. Rajab: A sacred month The month of Rajab is one of the sacred months of which Allah says (interpretation of the meaning): “Verily, the number of months with Allah is twelve months (in a year), so was it ordained by Allah on the Day when He created the heavens and the earth; of them four are Sacred (i.e. the 1st, the 7th, the 11th and the 12th months of the Islamic calendar). That is the right religion, so wrong not yourselves therein.” [al-Tawbah 9:36] What are the sacred months? 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. Why are the sacred months given this name? These months are called sacred for two reasons: Because fighting therein is forbidden unless initiated by the enemy Because transgression of the sacred limits therein is worse than at other times. Hence Allah has forbidden us to commit sins during these months, as He says (interpretation of the meaning): “Wrong not yourselves therein.” [al-Tawbah 9:36] Although committing sins is haram and forbidden during these months and at other times, in these months it is more forbidden. Al-Sa’di (may Allah have mercy on him) said (p. 373): In the phrase “wrong not yourselves therein”, the pronoun may be understood as referring to twelve months. Allah states that He has made them a measure of time for His slaves, which they may use for worshipping Him, and thank Allah for His blessings, and they serve the interests of His slaves, so beware of wronging yourselves therein. The pronoun may also be understood as referring to the four sacred months, and this forbids them to wrong themselves in those months in particular, as well as it being forbidden to do wrong at all times, because it is more forbidden at this time, but it is worse at this time than at others. End quote. Any hadith about fasting in Rajab? With regard to fasting in the month of Rajab, there is no sahih hadith to indicate that there is any special virtue in fasting all or part of this month. 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. Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him) said in Majmu’ al-Fatawa (25/290): “As for fasting in Rajab in particular, the ahadith concerning that are all da’if (weak), and in fact mawdu’ (fabricated). The scholars do not rely on any of them. They are not among the da’if ahadith which have been narrated concerning virtues, rather most of them are fabricated and false. In al-Musnad and elsewhere there is a hadith which says that the Prophet (peace and blessings of Allah be upon him) enjoined fasting the sacred months, namely Rajab, Dhu’l-Qa’dah, Dhu’l-Hijjah and Muharram, but this has to do with fasting during all of them, not just Rajab.” Ibn al-Qayyim (may Allah have mercy on him) said: “Every hadith which mentions fasting in Rajab and praying during some of its nights is false and fabricated.” (Al-Manar al-Munif, p. 96) Al-Hafiz ibn Hajar said in Tabyin al-‘Ajab (p. 11) “There is no sahih hadith that would count as evidence which speaks of the virtue of the month of Rajab, or that speaks of fasting this month or part of it, or of spending any particular night of it in prayer.” Shaykh Sayyid Sabiq (may Allah have mercy on him) said in Fiqh al-Sunnah (1/282): “Fasting in Rajab is no better than fasting in any other month, except that it is one of the sacred months. There is no report in the sahih Sunnah to suggest that there is anything special about fasting in this month. Whatever has been narrated concerning that is not fit to be quoted as evidence.” Fasting on 27 th Rajab: Any merits? Shaykh Ibn ‘Uthaymin (may Allah have mercy on him) was asked about fasting on the twenty-seventh of Rajab and spending that night in prayer. He replied: “Fasting on the twenty-seventh of Rajab and spending that night in prayer is a bid’ah (innovation), and every bid’ah is a going astray.” (Majmu’ Fatawa Ibn ‘Uthaymin, 20/440) For more about issues related to the month of Rajab, please see these answers: 36766 , 171509 , 114424 , and 202017 And Allah knows best. |

Praise be to Allaah It is permissible for a menstruating woman to recite Qur’aan according to the more correct scholarly opinion, especially if she needs to do that for fear of forgetting (what she had memorised), or to study for a test, or to seek healing thereby, on condition that she does not touch the Mus'haf (A Qur'an with Arabic text only), because no one should touch it except one who is in a state of purity. If she needs to read from the Mus'haf, she may touch it with a barrier, such as a piece of clean cloth or a handkerchief or gloves and the like. Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him) said: It is obvious that women used to menstruate at the time of the Messenger of Allah (SalAllaahu 'alaihi wa sallam) and he did not forbid them to recite Qur’aan. He also did not forbid them to recite dhikr (remembrance of Allah) or du‘a (supplication). In fact he instructed the menstruating women to go out on the day of Eid and recite takbeer with the Muslims. End quote. Majmoo‘ al-Fataawa, 21/460 He also said: There is no Sunnah at all forbidding (the menstruating woman) to recite Qur’aan. Women used to menstruate at the time of the Messenger of Allah {SalAllaahu 'alaihi wa sallam}, and if reciting was haraam for them, as prayer is, then this would have been one of the things that the Prophet {SalAllaahu 'alaihi wa sallam} forbade to his ummah, and the Mothers of the Believers would have known of it, and it would have been one of the things that they transmitted to the people. Based on that, there is nothing wrong with the menstruating woman memorize or performing ruqyah for herself by reciting Qur’aan, du‘aa’s and dhikr that are prescribed in Islam. There is also nothing wrong with her reciting from the Mus'haf, on condition that she does not touch the Mus'haf except with a barrier. The mobile phones in which Qur’aan is put in written or recorded form do not come under the same ruling as the Mus'haf, so it is permissible to touch them without having purified oneself and it is permissible to take them into the washroom with one, because writing Qur’aan on the mobile phone is not like writing it in a Mus'haf. It takes the form of waves that appear and disappear, and its letters are not fixed, and the mobile phone may contain Qur’aan and other things. Reading Qur’aan on a mobile phone makes it easy for women who are menstruating and one who cannot easily carry a Mus'haf with him, or one who is in a place where it is difficult for him to do wudoo’, because it is not essential for the one who touches it to be in a state of purity, as mentioned above. And Allah knows best. |

What is Valentine? Valentine’s Day is a jaahili Roman festival, which continued to be celebrated until after the Romans became Christian. This festival became connected with the saint known as Valentine who was sentenced to death on 14 February 270 CE. Some non-Muslims (including some Muslims) still celebrate this festival, during which immorality and evil are practised widely. Ina Lilah was ina ilae rojiun! Listen, as a Muslim reading this, it is not permissible for a Muslim to celebrate any of the festivals of the kuffaar, because festivals come under the heading of shar’i issues which are to be based on the sound texts. Shaykh al-Islam Ibn Taymiyah (may Allaah have mercy on him) said: Festivals are part of sharee’ah, clear way and rituals of which Allaah says (interpretation of the meaning): “To each among you, We have prescribed a law and a clear way” [Al-Quran al-Maa’idah 5:48] In essence, Muslims should not do any of their rituals at the time of their festivals; rather the day of their festival should be like any other day for the Muslims. The Muslims should not do anything specific in imitation of them. ( Majmoo al-Fataawa (25/329). ) Also, many scholars have issued fatawah stating that it is haraam to celebrate Valentine’s Day. Among them is our noble Sheikh: Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) who was asked: In recent times the celebration of Valentine’s Day has become widespread, especially among female students. It is a Christian festival where people dress completely in red, including clothes and shoes, and they exchange red flowers. We hope that you can explain the ruling on celebrating this festival, and what your advice is to Muslims with regard to such matters; may Allaah bless you and take care of you. He replied: Celebrating Valentine’s Day is not permissible for a number of reasons. 1- It is an innovated festival for which there is no basis in Islam. 2- It promotes love and infatuation. 3- It calls for hearts to be preoccupied with foolish matters that are contrary to the way of the righteous salaf (may Allaah be pleased with them). It is not permissible on this day to do any of the things that are characteristic of this festival, whether that has to do with food, drinks, clothing, exchanging gifts or anything else. The Muslim should be proud of his religion and should not be a weak character who follows every Tom, Dick and Harry. I ask Allaah to protect the Muslims from all temptations, visible and invisible, and to protect us and guide us. End quote from Majmoo’ Fataawa al-Shaykh Ibn ‘Uthaymeen (16/199) Say no to Valentine! May Allah grant us beneficial understanding (Ameen). Culled from Islam Q & A

According to the counting of Sultan, today is the 9th day of Rajab 1434AH. It was traced to the early generations (salaf) that the month of Rajab is the month of planting the seeds. Which seeds are we expected to plant? On this thread, you are going to understand the type of seeds as adapted from IslamQA The month of Rajab is one of the sacred months concerning which Allah, may He be exalted, says (interpretation of the meaning):https://islamqa.info/en/answers/332295/rajab-is-the-month-of-planting |
