عَنِ ابْنِ عَبَّاسٍ قَالَ: أُوحِيَ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: (نساوكم حرث لكم فَأتوا حَرْثكُمْ) الْآيَةَ: «أَقْبِلْ وَأَدْبِرْ وَاتَّقِ الدُّبُرَ وَالْحَيْضَةَ» . رَوَاهُ التِّرْمِذِيّ وَابْن مَاجَه

Abu Huraira reported God’s Messenger as saying, “He who has intercourse with his wife through her anus is accursed.” Ahmad and Abu Dawud transmitted it.
