Sahih Muslim Book - 2, Hadith - 630

و حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ وَعَلِيُّ بْنُ خَشْرَمٍ جَمِيعًا عَنْ عِيسَى بْنِ يُونُسَ قَالَ إِسْحَاقُ أَخْبَرَنَا عِيسَى حَدَّثَنَا الْأَعْمَشُ عَنْ مُسْلِمٍ عَنْ مَسْرُوقٍ عَنْ الْمُغِيرَةِ بْنِ شُعْبَةَ قَالَ خَرَجَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِيَقْضِيَ حَاجَتَهُ فَلَمَّا رَجَعَ تَلَقَّيْتُهُ بِالْإِدَاوَةِ فَصَبَبْتُ عَلَيْهِ فَغَسَلَ يَدَيْهِ ثُمَّ غَسَلَ وَجْهَهُ ثُمَّ ذَهَبَ لِيَغْسِلَ ذِرَاعَيْهِ فَضَاقَتْ الْجُبَّةُ فَأَخْرَجَهُمَا مِنْ تَحْتِ الْجُبَّةِ فَغَسَلَهُمَا وَمَسَحَ رَأْسَهُ وَمَسَحَ عَلَى خُفَّيْهِ ثُمَّ صَلَّى بِنَا.

It was narrated that Al-Mughirah bin Shu'bah said: "The Messenger of Allah (s.a.w) went out to relieve himself. When he came back I met him with the vessel and poured water for him. He washed his hands, then he washed his face, then he tried to wash his arms but the (sleeves of the) cloak was too narrow, so he brought his arms out from beneath the cloak and washed them, and he wiped his head and wiped over his Khuff, then he led us in prayer."
