Allah has already forgiven the Prophet and the Muhajireen and the Ansar who followed him in the hour of difficulty after the hearts of a party of them had almost inclined [to doubt], and then He forgave them. Indeed, He was to them Kind and Merciful. (Quran 9:117)
It is He who sends down upon His Servant [Muhammad] verses of clear evidence that He may bring you out from darkness’s into the light. And indeed, Allah is to you Kind and Merciful. (Quran 57:9)
And [there is a share for] those who came after them, saying, “Our Lord, forgive us and our brothers who preceded us in faith and put not in our hearts [any] resentment toward those who have believed. Our Lord, indeed You are Kind and Merciful.” (Quran 59:10)
