Question: How should we call people to Islam?

Praise be to Allah.A

Calling others to Islam is an honourable mission. This is the work of the Prophets and Messengers. The Messenger (peace and blessings of Allaah be upon him) explained that his mission in life, and the mission of his followers, is to call people to Allaah.

Allaah says (interpretation of themeaning):
“Say (O Muhammad): ‘This is my way; I invite unto Allaah (i.e. to the Oneness of Allaah — Islamic Monotheism) with sure knowledge, I and whosoever follows me (also must invite others to Allaah, i.e. to the Oneness of Allaah — Islamic Monotheism with sure knowledge). And Glorified and Exalted be Allaah (above all that they associate as partners with Him). And I am not of the Mushrikoon (polytheists, pagans, idolaters and disbelievers in the Oneness of Allaah; those who worship others along with Allaah or set up rivals or partners to Allaah)’”[Yoosuf 12:108]

The Muslims in general and the scholars in particular are commanded to call people to Islam, as Allaah says

(interpretation of the meaning):
“Let there arise out of you a group of people inviting to all that is good (Islam), enjoining Al-Ma‘roof (i.e. Islamic Monotheism and all that Islam orders one to do) and forbidding Al-Munkar (polytheism and disbelief and all that Islam has forbidden). And it is they who are the successful”[Aal ‘Imraan 3:104]

The Prophet (peace and blessings of Allaah be upon him) said: “Convey from me even if it is (only) one aayah.” (Narrated by al-Bukhaari, 3461)
Calling people to Allaah is an important task and a glorious mission, because it means calling people to worship Allaah alone. It means bringing them forth from darkness to the light, planting goodness in the place of evil and truth in the place of falsehood. Hence whoever does this needs to have knowledge, understanding, patience, forbearance, gentleness and kindness. He needs to give of his wealth and of himself, and he needs to understand people’s circumstances and habits.

Allaah says (interpretation of the meaning):
“Invite (mankind, O Muhammad) to the way of your Lord (i.e. Islam) with wisdom (i.e. with the Divine Revelation and the Qur’aan) and fair preaching, and argue with them in a way that is better. Truly, your Lord knows best who has gone astray from His path, and He is the Best Aware of those who are guided”
[al-Nahl 16:125]

Allaah blessed His Messenger with the words (interpretation of the meaning):

“And by the Mercy of Allaah, you dealt with them gently. And had you been severe and harsh-hearted, they would have broken away from about you; so pass over (their faults), and ask (Allaah’s) forgiveness for them; and consult them in the affairs”
[Aal ‘Imraan 3:159]

The daa’iyah (caller) may be faced with debates in his da’wah activities, especially with the People of the Book. Allaah has commanded us, if it reaches the point of debate, to debate in a manner that is better, which is with kindness and gentleness, explaining the principles of Islam as they came, pure and simple, in a kindly manner and with no element of compulsion.

Allaah says :
“And argue not with the people of the Scripture (Jews unless it be in (a way) that is better (with good words and in good manner, inviting them to Islamic Monotheism with His Verses), except with such of them as do wrong; and say (to them): ‘We believe in that which has been revealed to us and revealed to you; our Ilaah (God) and your Ilaah (God) is One (i.e. Allaah), and to Him we have submitted (as Muslims)’”
[al-‘Ankaboot 29:46]

Calling people to Allaah is a virtuous deed which brings great reward. The Prophet (peace and blessings of Allaah be upon him) said: “Whoever calls others to guidance will have a reward like the rewards of those who follow him, without that detracting from their reward in any way. And whoever calls others to misguidance will have a burden of sin like the burden of those who follow him, without that detracting from their burden in any way.”(Narrated by Muslim, 2674)

The Messenger (peace and blessings of Allaah be upon him) called people to Islam, patiently bearing the persecution of the kuffaar, Jews and hypocrites. They made fun of him and disbelieved in him; they insulted him and threw stones at him; they said that he was a sorcerer or a madman; they accused him of being a poet or a soothsayer – but he (peace and blessings of Allaah be upon him) bore all that with patience until Allaah granted him victory and caused His religion to prevail. So the daa’iyah (preacher) must follow his example:

“So be patient (O Muhammad). Verily, the Promise of Allaah is true; and let not those who have no certainty of Faith discourage you from conveying Allaah’s Message (which you are obliged to convey)[al-Room 30:60 – interpretation of the meaning]
The Muslims must follow the example and guidance of their Messenger and call others to Islam, bearing insults and harm with patience for the sake of Allaah, as their Messenger did.
“Indeed in the Messenger of Allaah (Muhammad) you have a good example to follow for him who hopes for (the Meeting with) Allaah and the Last Day, and remembers Allaah much”

[al-Ahzaab 33:21 – interpretation of the meaning]
The well-being and happiness of this ummah are only to be found in following this religion. Hence Allaah commanded us to convey the message to all of mankind, as He says

(interpretation of the meaning):
“This (Qur’aan) is a Message for mankind (and a clear proof against them), in order that they may be warned thereby, and that they may know that He is the only One Ilaah (God — Allaah) — (none has the right to be worshipped but Allaah) — and that men of understanding may take heed [Ibraaheem 14:52]

As'salamu alaykum to all my muslims brother. how many non-muslims have you invited to islam? how many of your invitees have accepted islam? how many people have you recommend reading of Quran to? it is unfortunate that what we supposed to be doing to non-muslims, non-muslims are doing it to us. i was listening to a radio program during Ramadan, a new to convert to islam was invited, an ex pastor precisely. what he said makes me shiver and cry. he narrated how the first verse he read from the Quran makes him to be curious to read more, hence he start reading it. he said "we (muslims) have gold and did'nt publicize it, you muslims didn't publicize it enough". he said what he was told about Quran as a young christian was so disastrous this word shocked me so much and i pray to Allah that night to give the more power to publicize his mighty Words (Quran)

please let's start publicizing Quran. invite people to read it, enjoin what is good and forbid what is bad. May Allah make easy our matters here and hereafter Ameen.

(Q.41.33) And who is better in speech than one who invites to Allah and does righteousness and says, "Indeed, I am of the Muslims."
