'Aayeshah Radiyallahu 'Anha says:
"I have never seen Rasulullah Sallallahu 'Alayhi Wasallam avenge himself for a personal affliction, but if one transgressed a prohibited thing from those prohibited by Allah, (To commit a haraam act. The commentators on hadith say the rights of man are also included) then there was no one more angry than Rasulullah Sallallahu 'Alayhi Wasallam. Whenever Rasulullah Sallallahu 'Alayhi Wasallam was given a choice between two things, he always chose the one that was simple, if it did not lead to any type of sin".
