Qur'an al-i-'Imran 3:159: So by mercy from Allah , [O Muhammad], 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 Allah . Indeed, Allah loves those who rely [upon Him].
Jabir narrated that : the Messenger of Allah said: “There is none who utters a supplication, except that Allah gives him what he asked, or prevents evil from him that is equal to it – as long as he does not supplicate for something evil, or the cutting of ties of the womb.” Reference : Jami` at-Tirmidhi 3381 In-book reference : Book 48, Hadith 12 English translation : Vol. 6, Book 45, Hadith 3381
