(44) باب مَا يُؤْمَرُ بِهِ مِنْ غَضِّ الْبَصَرِ
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."
