عَنْ عُمَارَةَ بْنِ عُثْمَانَ بْنِ حُنَيْفٍ حَدَّثَنِي الْقَيْسِيُّ أَنَّهُ كَانَ مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فِي سَفَرٍ فَبَالَ فَأُتِيَ بِمَاءٍ فَهَالَ عَلَى يَدِهِ مِنَ الْإِنَاءِ فَغَسَلَهَا مَرَّةً وَعَلَى وَجْهِهِ مَرَّةً وَعَلَى ذِرَاعَيْهِ مَرَّةً وَغَسَلَ رِجْلَيْهِ مَرَّةً بِيَدَيْهِ كِلْتَيْهِمَا، وَقَالَ فِي حَدِيثِهِ: الْتَفَّ إِصْبَعَهُ الْإِبْهَامَ
It is narrated from Sayyiduna Qaisi (may Allah be pleased with him) that he was on a journey with the Messenger of Allah (peace and blessings be upon him). The Prophet (peace and blessings be upon him) urinated, then water was brought to him. The Prophet (peace and blessings be upon him) poured water from the vessel onto his hand and washed it once, washed his face once, washed his arms once, and washed both feet once with both hands. In his narration, he said: The finger was wrapped with the thumb.
