Sunan of Abu Dawood Book 12, Hadith 2153

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 ‏"‏ ‏.‏

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."
