Narrated Amr ibn Shu'aib, from his father, from his grandfather: A man asked the Prophet ﷺ, "What makes ghusl obligatory except for semen?" He replied: "When the circumcised parts meet and the glans of the penis is inside, ghusl becomes obligatory, whether or not semen is released." [Narrated by Tabarani in his Al-Awsat and Imam Abu Muhammad Abdullah ibn Wahb in his Mustadrak, with a similar narration.)
