Sahih al-Bukhari 6786
Narrated Aisha:
Whenever the Prophet (ﷺ) was given an option between two things, he used to select the easier of the tow 
as long as it was not sinful; but if it was sinful, he would remain far from it. By Allah, he never took 
revenge for himself concerning any matter that was presented to him, but when Allah's Limits were 
transgressed, he would take revenge for Allah's Sake.
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ مَا خُيِّرَ النَّبِيُّ صلى الله عليه وسلم بَيْنَ أَمْرَيْنِ إِلاَّ اخْتَارَ أَيْسَرَهُمَا، مَا لَمْ يَأْثَمْ، فَإِذَا كَانَ الإِثْمُ كَانَ أَبْعَدَهُمَا مِنْهُ، وَاللَّهِ مَا انْتَقَمَ لِنَفْسِهِ فِي شَىْءٍ يُؤْتَى إِلَيْهِ قَطُّ، حَتَّى تُنْتَهَكَ حُرُمَاتُ اللَّهِ، فَيَنْتَقِمُ لِلَّهِ‏.‏
