I set out with the Messenger of Allah ﷺ on one of his journeys. We traveled until, in the last part of the night, he went off until he was out of sight to relieve himself. Then he came back and called for water for purification. He was wearing a Syrian cloak with narrow sleeves, so he slipped his hand out from underneath the cloak, then washed his face and his hands, wiped his head, and wiped over his leather socks.
حدثنا هشام بن عبد الملك حدثنا عبيد الله بن إياد قال سمعت إيادا يحدث عن قبيصة بن برمة
خرجت مع رسول الله ﷺ في بعض ما كان يسافر فسرنا حتى إذا كنا في وجه السحر انطلق حتى توارى عني فضرب الخلاء ثم جاء فدعا بطهور وعليه جبة شامية ضيقة الكمين فأدخل يده من أسفل الجبة ثم غسل وجهه ويديه ومسح برأسه ومسح على الخفين
Its isnad is sahih. Ubaydullah bin Iyad bin Laqeet Sadusi is reliable, as is his father, and their hadith is found in Muslim. The hadith was mentioned previously at 18052.
