Musannaf Ibn Abi Shaybah

Hazrat Ibn Abbas (may Allah be pleased with them) narrates that I went to Hazrat Ubayy, and Hazrat Umar was also present with him. I said that I felt madhi (pre-seminal fluid), so I washed my private part. Hazrat Umar asked, "Is this sufficient for you?" I said, "Yes." He said, "Did you hear this from the Messenger of Allah?" I replied, "Yes."
