The Prophet ﷺ said, "Every son of Adam has his share of fornication," and he mentioned this account. He said, "The hands commit fornication, and their fornication is grasping. The feet commit fornication, and their fornication is walking. The mouth commits fornication, and its fornication is kissing."
حدثنا موسى بن إسمعيل حدثنا حماد عن سهيل بن أبي صالح عن أبيه
أن النبي ﷺ قال لكل ابن آدم حظه من الزنا بهذه القصة قال واليدان تزنيان فزناهما البطش والرجلان تزنيان فزناهما المشي والفم يزني فزناه القبل
[Its chain is sahih] Ahmad narrated it: 2/343, from the hadith of Hammad bin Salama, and Muslim, in Qadr, chapter "The measure decreed upon Ibn Adam of his share of fornication and other things," no. 2657, from the hadith of Suhayl bin Abu Salih, through him.
