From Sahih Muslim (Hadith 723):
This hadith is narrated by A'mash with the same chain of transmitters, but in the hadith narrated by Yahya b. Yahya and Abu Kuraib there is no mention of:" Pouring of three handfuls of water on the head." and in the hadith narrated by Waki' all the features of ablution have been recorded: rinsing (of mouth), snuffing of water (in the nostrils) ; and in the hadith transmitted by Abu Mu'awyia, there is no mention of a towel
