Mughira b. Shu'ba reported:
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، وَأَبُو كُرَيْبٍ قَالَ أَبُو بَكْرٍ حَدَّثَنَا أَبُو مُعَاوِيَةَ ، عَنِ الأَعْمَشِ ، عَنْ مُسْلِمٍ ، عَنْ مَسْرُوقٍ ، عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ ، قَالَ كُنْتُ مَعَ النَّبِيِّ صلى الله عليه وسلم فِي سَفَرٍ فَقَالَ " يَا مُغِيرَةُ خُذِ الإِدَاوَةَ " . فَأَخَذْتُهَا ثُمَّ خَرَجْتُ مَعَهُ فَانْطَلَقَ رَسُولُ اللَّهِ صلى الله عليه وسلم حَتَّى تَوَارَى عَنِّي فَقَضَى حَاجَتَهُ ثُمَّ جَاءَ وَعَلَيْهِ جُبَّةٌ شَامِيَّةٌ ضَيِّقَةُ الْكُمَّيْنِ فَذَهَبَ يُخْرِجُ يَدَهُ مِنْ كُمِّهَا فَضَاقَتْ عَلَيْهِ فَأَخْرَجَ يَدَهُ مِنْ أَسْفَلِهَا فَصَبَبْتُ عَلَيْهِ فَتَوَضَّأَ وُضُوءَهُ لِلصَّلاَةِ ثُمَّ مَسَحَ عَلَى خُفَّيْهِ ثُمَّ صَلَّى .
I was in the company of the Messenger of Allah (ﷺ) on a journey when he said: Mughira take hold of this jar (of water). I took hold of it and I went out with him. (I stopped but) the Messenger of Allah (ﷺ) proceeded on till he was out of my sight. He relieved himself and then came back and he was wearing a tight-sleeved Syrian gown. He tried to get his forearms out. but the sleeve of the gown was very narrow, so he brought his hands out from under the gown. I poured water over (his hands) and he performed ablution for prayer, then wiped over his socks and prayed.
