Sunan Abi Dawud

Narrated Anas ibn Malik: I saw the Apostle (ﷺ) would descend from the pulpit and a man stop him for his need. He would remain standing with him until his need was fulfilled. Then he would stand and pray. Abu Dawud said: This tradition is not well known from the narrator Thabit. Jarir b. Hazim is the only narrator of this tradition
