Narrated `Aisha:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ ، عَنْ مَالِكٍ ، عَنِ ابْنِ شِهَابٍ ، عَنْ عُرْوَةَ ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّهَا قَالَتْ مَا خُيِّرَ رَسُولُ اللَّهِ صلى الله عليه وسلم بَيْنَ أَمْرَيْنِ قَطُّ إِلاَّ أَخَذَ أَيْسَرَهُمَا، مَا لَمْ يَكُنْ إِثْمًا، فَإِنْ كَانَ إِثْمًا كَانَ أَبْعَدَ النَّاسِ مِنْهُ، وَمَا انْتَقَمَ رَسُولُ اللَّهِ صلى الله عليه وسلم لِنَفْسِهِ فِي شَىْءٍ قَطُّ، إِلاَّ أَنْ تُنْتَهَكَ حُرْمَةُ اللَّهِ، فَيَنْتَقِمَ بِهَا لِلَّهِ.
Whenever Allah's Messenger (ﷺ) was given the choice of one of two matters he would choose the easier of the two as long as it was not sinful to do so, but if it was sinful, he would not approach it. Allah's Apostle never took revenge over anybody for his own sake but (he did) only when Allah's legal bindings were outraged, in which case he would take revenge for Allah's sake." (See Hadith No. 760. Vol. 4)
