'Aishah (May Allah be pleased with her) reported:
Whenever the Prophet (ﷺ) was given a choice between two matters, he would (always) choose the easier as long as it was not sinful to do so; but if it was sinful he was most strict in avoiding it. He never took revenge upon anybody for his own sake; but when Allah's Legal Bindings were outraged, he would take revenge for Allah's sake.[Al- Bukhari and Muslim].
