Sunan Ibn Majah, Book 1, Hadith 421 (In-Book) ⓘ

It was narrated that Mughirah bin Shu'bah said: "The Prophet went out to relieve himself and when he came back, I met him with a water skin and poured water for him. He washed his hands and his face, then he went to wash his forearms but his garment was too tight, so he brought his arms out from underneath his garment and washed them, then he wiped over his leather socks, then he led us in prayer."

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا عِيسَى بْنُ يُونُسَ، حَدَّثَنَا الأَعْمَشُ، عَنْ مُسْلِمِ بْنِ صُبَيْحٍ، عَنْ مَسْرُوقٍ، عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ، قَالَ خَرَجَ النَّبِيُّ ـ صلى الله عليه وسلم ـ لِبَعْضِ حَاجَتِهِ فَلَمَّا رَجَعَ تَلَقَّيْتُهُ بِالإِدَاوَةِ فَصَبَبْتُ عَلَيْهِ فَغَسَلَ يَدَيْهِ ثُمَّ غَسَلَ وَجْهَهُ ثُمَّ ذَهَبَ يَغْسِلُ ذِرَاعَيْهِ فَضَاقَتِ الْجُبَّةُ فَأَخْرَجَهُمَا مِنْ تَحْتِ الْجُبَّةِ فَغَسَلَهُمَا وَمَسَحَ عَلَى خُفَّيْهِ ثُمَّ صَلَّى بِنَا ‏.‏
