Umair, the freed slave of Ibn Abbas, said that he heard him say: I and Abdullah bin Yasar, the freed slave of Maimunah, wife of the Prophet صلی اللہ علیہ وسلم, came and entered upon Abu al-Juhaim bin al-Harith bin al-Simmat al-Ansari. Abu al-Juhaim said: The Messenger of Allah صلی اللہ علیہ وسلم came from Bir Jamal (a place near Madina) and a man met him and saluted him. The Messenger of Allah صلی اللہ علیہ وسلم did not return the salutation until he came to a wall and wiped his face and hands and then returned the salutation (i. e. after performing tayammum).
