Hadith 2328
'A'isha reported that Allah's Messenger (may peace be upon him) never beat anyone with his hand, neither a woman nor a servant, but only, in the case when he had been fighting in the cause of Allah and he never took revenge for anything unless the things made inviolable by Allah were made violable; he then took revenge for Allah, the Exalted and Glorious.
حَدَّثَنَاهُ أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ مَا ضَرَبَ رَسُولُ اللَّهِ صلى الله عليه وسلم شَيْئًا قَطُّ بِيَدِهِ وَلاَ امْرَأَةً وَلاَ خَادِمًا إِلاَّ أَنْ يُجَاهِدَ فِي سَبِيلِ اللَّهِ وَمَا نِيلَ مِنْهُ شَىْءٌ قَطُّ فَيَنْتَقِمَ مِنْ صَاحِبِهِ إِلاَّ أَنْ يُنْتَهَكَ شَىْءٌ مِنْ مَحَارِمِ اللَّهِ فَيَنْتَقِمَ لِلَّهِ عَزَّ وَجَلَّ .
