"I was a guest (at the home) of 'Umar one night, and in the middle of the night he went and hit his wife, and I separated them. When he went to bed he said to me: 'O Ash'ath, learn from me something that I heard from the Messenger of Allah" A man should not be asked why he beats his wife, and do not go to sleep until you have prayed the Witr."' And I forgot the third thing."  

ضِفْتُ عُمَرَ لَيْلَةً فَلَمَّا كَانَ فِي جَوْفِ اللَّيْلِ قَامَ إِلَى امْرَأَتِهِ يَضْرِبُهَا فَحَجَزْتُ بَيْنَهُمَا فَلَمَّا أَوَى إِلَى فِرَاشِهِ قَالَ لِي يَا أَشْعَثُ احْفَظْ عَنِّي شَيْئًا سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ ﷺ لاَ يُسْأَلُ الرَّجُلُ فِيمَ يَضْرِبُ امْرَأَتَهُ وَلاَ تَنَمْ إِلاَّ عَلَى وِتْرٍ وَنَسِيتُ الثَّالِثَةَ حَدَّثَنَا مُحَمَّدُ بْنُ خَالِدِ بْنِ خِدَاشٍ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ حَدَّثَنَا أَبُو عَوَانَةَ بِإِسْنَادِهِ نَحْوَهُ
