وَٱلَّذِينَ يُظَـٰهِرُونَ مِن نِّسَآئِهِمْ ثُمَّ يَعُودُونَ لِمَا قَالُوا فَتَحْرِيرُ رَقَبَةٍ مِّن قَبْلِ أَن يَتَمَآسَّا ۚ ذَٰلِكُمْ تُوعَظُونَ بِهِۦ ۚ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ

Wallatheena yuthahiroonamin nisa-ihim thumma yaAAoodoona lima qaloofatahreeru raqabatin min qabli an yatamassa thalikumtooAAathoona bihi wallahu bimataAAmaloona khabeer
