IBNHIBBAN 1347:
from Ḥamzah b. al-Mughīrah b. Shuʿbah from his father —
[Machine] The Prophet ﷺ set off, and Al-Mughirah bin Shu'bah accompanied him. When the Prophet ﷺ finished his business, he said, "Do you have water?" I said yes, and I brought him a bowl. He washed his hands and face, then reached beneath his garment to wash his arms. The sleeves of his garment became tight, so he pulled out his hand from underneath the garment and placed it on his shoulder. He washed his arms and wiped over his feet and turban. Then, he mounted his ride, and I mounted with him. We reached the people, and Abdullah bin Awf had already led them in one Rak'ah prayer. When he realized that the Prophet ﷺ had arrived, he intended to step back, but the Prophet ﷺ gestured to him to continue praying. When Abdullah bin Awf finished the prayer, the Prophet ﷺ and Al-Mughirah both stood up and completed what they had missed.

عن حمزه بن المغيره بن شعبه عن أبيه —
أَنَّ النَّبِيَّ ﷺ تَخَلَّفَ فَتَخَلَّفَ مَعَهُ الْمُغِيرَةُ بْنُ شُعْبَةَ فَلَمَّا قَضَى حَاجَتَهُ قَالَ «هَلْ مَعَكَ مَاءٌ؟ » قُلْتُ فَأَتَيْتُهُ بِالْمَطْهَرَةِ «فَغَسَلَ كَفَّيْهِ وَوَجْهَهُ ثُمَّ ذَهَبَ لِيَحْسِرَ عَنْ ذِرَاعَيْهِ فَضَاقَتْ بِهَا الْجُبَّةُ فَأَخْرَجَ يَدَهُ مِنْ تَحْتِ الْجُبَّةِ فَأَلْقَاهَا عَلَى عَاتِقِهِ فَغَسَلَ ذِرَاعَيْهِ وَمَسَحَ عَلَى خُفَّيْهِ وَعِمَامَتِهِ ثُمَّ رَكِبَ وَرَكِبْتُ مَعَهُ فَانْتَهَى إِلَى النَّاسِ وَقَدْ صَلَّى بِهِمْ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ رَكْعَةً فَلَمَّا أَحَسَّ بِجَيْئَةِ النَّبِيِّ ﷺ ذَهَبَ لِيَتَأَخَّرَ فَأَوْمَأَ إِلَيْهِ النَّبِيُّ ﷺ أَنْ صَلِّ فَلَمَّا قَضَى عَبْدُ الرَّحْمَنِ الصَّلَاةَ قَامَ النَّبِيُّ ﷺ وَالْمُغِيرَةُ فَأَكْمَلَا مَا سَبَقَهُمَا»
