It was narrated that Al-Mughirah bin Shu'bah said:"The Prophet (ﷺ) went out to relieve himself, and when he came back, I met him with a vessel (of water). I poured some for him and he washed his hands, then he washed his face. Then he wanted to wash his forearms but his Jubbah was too tight, so he brought them out from beneath the Jubbah to wash them, and he wiped over his Khuffs, then he led us in prayer
