The Prophet ﷺ went out to relieve himself. When he returned, I met him with a water vessel and poured water for him. He washed his hands, then washed his face, then went to wash his forearms, but the sleeves of his cloak were too narrow. So he pulled his arms out from underneath the cloak and washed them, then wiped over his leather socks, and then led us in prayer.
حدثنا هشام بن عمار حدثنا عيسى بن يونس حدثنا الأعمش عن مسلم بن صبيح عن مسروق
خرج النبي ﷺ لبعض حاجته فلما رجع تلقيته بالإداوة فصببت عليه فغسل يديه ثم غسل وجهه ثم ذهب يغسل ذراعيه فضاقت الجبة فأخرجهما من تحت الجبة فغسلهما ومسح على خفيه ثم صلى بنا
