Hadith 10:184
‘Umar reported the Prophet as saying, “A man will not be asked about why he beat his wife.” Abu Dawud and Ibn Majah transmitted it.
وَعَنْ عُمَرَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «لَا يُسْأَلُ الرَّجُلُ فِيمَا ضَرَبَ امْرَأَتَهُ عَلَيْهِ» . رَوَاهُ أَبُو دَاوُد وَابْن مَاجَه
