Hadith 3:102
‘Abdallah b. ‘Abbas said that God’s messenger performed each detail of his ablution once, doing no more than that. Bukhari transmitted it.
وَعَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ قَالَ: تَوَضَّأَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَرَّةً مَرَّةً لَمْ يَزِدْ عَلَى هَذَا. رَوَاهُ الْبُخَارِيُّ
