al-Laith bin Sa'd الليث بن سعد · Marriage (Kitab Al-Nikah)

A’ishah wife of the Prophet (ﷺ) reported “When the Apostle of Allaah(ﷺ) intended to go on a journey he cast lots amongst his wives and the one who was chosen by lot went on it with him. He divided his time, day and night (equally) for each of his wives except that Saudah daughter of Zam’ah gave her day to A’ishah.

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.”
