Hadith 5817
`A'isha said God's messenger was never given his choice between two things without taking the lesser of them provided it involved no sin, for if it did, no one kept farther away from it than he. And God's messenger never took revenge on his own behalf for anything unless something God had forbidden had been transgressed, in which event he took revenge for it for God's sake. (Bukhari and Muslim.)
وَعَنْ عَائِشَةَ قَالَتْ: مَا خُيِّرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَيْنَ أَمْرَيْنِ قَطُّ إِلَّا أَخَذَ أَيْسَرَهُمَا مَا لَمْ يَكُنْ إِثْمًا فَإِنْ كَانَ إِثْمًا كَانَ أَبْعَدَ النَّاسِ مِنْهُ وَمَا انْتَقَمَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِنَفْسِهِ فِي شَيْءٍ قَطُّ إِلَّا أَنْ يُنتهك حرمةُ الله فينتقم لله بهَا. مُتَّفق عَلَيْهِ
