حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ أَبِي إِسْحَاقَ، عَنْ سُلَيْمَانَ بْنِ صُرَدٍ، عَنْ جُبَيْرِ بْنِ مُطْعِمٍ، قَالَ تَمَارَوْا فِي الْغُسْلِ مِنَ الْجَنَابَةِ عِنْدَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ أَمَّا أَنَا فَأُفِيضُ عَلَى رَأْسِي ثَلاَثَ أَكُفٍّ ‏"‏ ‏.‏

It was narrated from Abu Hurairah that

A man asked him: "How much water should I pour over my head when I m sexually impure?" He said: "the messenger of Allah used to pour three handfuls of water over his head." The man said: "My hair is long." He said: "The Messenger of Allah had more hair than you and he was cleaner."
