'A’isha said: "I never saw Allah’s Messenger (Allah bless him and give him peace) take revenge for an outrage committed against him as long as none of the sacred prohibitions of Allah were violated, but if there was any violation of the sacred prohibitions of Allah, he would be enraged. Whenever he was given a choice between two matters, he would choose the easier of the two, provided it was not conducive to sin.”

حَدَّثَنَا أَحْمَدُ بْنُ عَبْدَةَ الضَّبِّيُّ، قَالَ: حَدَّثَنَا فُضَيْلُ بْنُ عِيَاضٍ، عَنْ مَنْصُورٍ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ: مَا رَأَيْتُ رَسُولَ اللهِ صلى الله عليه وسلم مُنْتَصِرًا مِنْ مَظْلَمَةٍ ظُلِمَهَا قَطُّ، مَا لَمْ يُنْتَهَكْ مِنْ مَحَارِمِ اللهِ تَعَالَى شَيْءٌ، فَإِذَا انْتُهِكَ مِنْ مَحَارِمِ اللهِ شَيْءٌ كَانَ مِنْ أَشَدِّهِمْ فِي ذَلِكَ غَضَبًا، وَمَا خُيِّرَ بَيْنَ أَمْرَيْنِ، إِلا اخْتَارَ أَيْسَرَهُمَا، مَا لَمْ يَكُنْ مَأْثَمًا.
