Calling people to Allah is a command, founded on wisdom and good instruction. The verses gathered here dwell above all on the obstacles the call meets, such as clinging to the customs of forefathers or the hold of desire over those invited, and stress the importance of knowledge for the caller and the rank of the Prophet Muhammad ﷺ as the foremost of callers.
Verses gathered from a topical index of the Quran, in Mushaf order; every verse is quoted in full.
So by mercy from Allāh, [O Muḥammad], you were lenient with them. And if you had been rude [in speech] and harsh in heart, they would have disbanded from about you. So pardon them and ask forgiveness for them and consult them in the matter. And when you have decided, then rely upon Allāh. Indeed, Allāh loves those who rely [upon Him].
