Sunan Ibn Majah, Hadith 541 ⓘ

It was narrated that Abu Darda' said: "The Messenger of Allah came out to us with water dripping from his head, and he led us in prayer wearing a single garment, placing its one end on the right shoulder, and the other end on the other shoulder. When he finished praying, 'Umar bin Khattab said to him: 'O Messenger of Allah, did you lead us in prayer wearing a single garment? He said: 'Yes, I perform prayer in it, and in it I (i.e. I had sexual intercourse in it)."
