Abu Hurairah reported the Prophet (ﷺ) as saying “ Every child of Adam has his share in adultery. He then narrated the rest of the tradition. This version goes “And the hands commit adultery; their adultery is catching; and the legs commit adultery; their adultery is walking; and the mouth commits adultery – its adultery is kissing.”
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " لِكُلِّ ابْنِ آدَمَ حَظُّهُ مِنَ الزِّنَا " . بِهَذِهِ الْقِصَّةِ قَالَ " وَالْيَدَانِ تَزْنِيَانِ فَزِنَاهُمَا الْبَطْشُ وَالرِّجْلاَنِ تَزْنِيَانِ فَزِنَاهُمَا الْمَشْىُ وَالْفَمُ يَزْنِي فَزِنَاهُ الْقُبَلُ " .
