He prayed Ad-Duha - but I do not know how many Rak'ahs he prayed - after he finished Ghusl.'"

← Previous Hadith "I used to perform Ghusl - the Messenger of Allah (ﷺ) and I - from one vessel. He would compete with me and I would with him (to take the water) until he would say: 'Leave me some,' and I would say, 'Leave me some.'"

Sunan an-Nasa'i Book 4, Hadith 19 Next Hadith → "I remember performing Ghusl - myself and the Messenger of Allah (ﷺ), from this" - a vessel like a Sa' or smaller. "We both started taking water from it and I poured water over my head with my hand, three times, without undoing any of my hair."
