Q 4: We have received two messages; one asks about the ideal way of calling to Allah (Glorified and Exalted be He) and the second is about the ideal way of enjoining good and forbidding evil. The people who wrote the two messages mention that they observe that Muslims make a lot of mistakes and they are feeling pain because of what they see. They wonder if there is something to do in order to stop evil; could you kindly advise.
A 4 : Allah (Glorified and Exalted be He) explains the way of calling and what a caller should do. Allah (may He be Praised and Glorified)
Say (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭ ﺳﻠﻢ): "This is my way; I invite unto Allâh (i.e. to the Oneness of Allâh Islâmic Monotheism) with sure knowledge, I and whosoever follows me (also must invite others to Allâh i.e. to the Oneness of Allâh Islâmic Monotheism with sure knowledge).
Invite (mankind, O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭ ﺳﻠﻢ) to the Way of your Lord (i.e. Islâm) with wisdom (i.e. with the Divine Revelation and the Qur'ân) and fair preaching, and argue with them in a way that is better.
And by the Mercy of Allâh, you dealt with them gently. And had you been severe and harshhearted, they would have broken away from about you
"And speak to him mildly, perhaps he may accept admonition or fear (Allâh)."
Kindness is not to be found in anything but that it adds to its beauty and it is not withdrawn from anything but it makes it defective.
He who is deprived of forbearance and gentleness is, in fact, deprived of all good.
And argue not with the people of the Scripture (Jews and Christians), unless it be in (a way) that is better (with good words and in good manner, inviting them to Islâmic Monotheism with His Verses), except with such of them as do wrong
Whoever, among you, sees something abominable should rectify it with his hand. If he has no strength enough to do it, then he should do it with his tongue and if he has no strength enough to do it, (even) then he should (abhor it) from his heart, and that is the least of Faith.
So keep your duty to Allâh and fear Him as much as you can
The believers, men and women, are Auliyâ' (helpers, supporters, friends, protectors) of one another; they enjoin (on the people) AlMa'rûf (i.e. Islâmic Monotheism and all that Islâm orders one to do), and forbid (people) from AlMunkar (i.e. polytheism and disbelief of all kinds, and all that Islâm has forbidden)
You [true believers in Islâmic Monotheism, and real followers of Prophet Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ) and his Sunnah] are the best of peoples ever raised up for mankind; you enjoin AlMa'rûf (i.e. Islâmic Monotheism and all that Islâm has ordained) and forbid AlMunkar (polytheism, disbelief and all that Islâm has forbidden), and you believe in Allâh.
Those among the Children of Israel who disbelieved were cursed by the tongue of Dâwûd (David) and 'Isâ (Jesus), son of Maryam (Mary). That was because they disobeyed (Allâh and the Messengers) and were ever transgressing beyond bounds. They used not to forbid one another from AlMunkar (wrong, evildoing, sins, polytheism, disbelief) which they committed. Vile indeed was what they used to do.
