Abdur Rahman bin 'Amr al-Awza'i عبد الرحمن بن عمرو أبو عمرو الأوزاعي · The Book on Purification

"Allah's Messenger vomited so he performed Wudu." So I met Thawban in a Masjid in Damascus, and I mentioned that to him. He said: 'He told the truth, I poured the water for his Wudu."

"When the circumcised meets the circumcised, then indeed Ghusl is required. Myself and Allah's Messenger did that, so we performed Ghusl."
