'A'isha said, "The Messenger of Allah, may Allah bless him andgrant him peace, was never given a choice between two things but that hechose the easier of the two as long as it was not a wrong action. If itwas a wrong action. then he was the last person to do it. The Messengerof Allah, may Allah bless him and grant him peace, never took revenge onhis own behalf. But when the respect of Allah Almighty was violated, hewould take revenge on behalf of Allah Almighty."
