Yasir, the freed slave of Maimuna, the wife of the Apostle (way peace be upon him). came to the house of Abu'l-Jahm b. al-Harith al-Simma Ansari and he said: The Messenger of Allah (may peace be upon him) came from the direction of Bi'r Jamal and a man met him; he saluted him but the Messenger of Allah (may peace be upon him) made no response, till he (the Holy Prophet) came to the wall, wiped his face and hands and then returned his salutations.
