It is narrated from Sayyiduna Anas (may Allah be pleased with him) that when the Noble Prophet (peace and blessings be upon him) would come out of the toilet, a boy would bring a small bucket of water with which the Prophet (peace and blessings be upon him) would perform istinja (cleaning). Imam Darimi Abu Muhammad (may Allah have mercy on him) said: Abu Mu'adh's name is Ata bin Mani' Abu Maymunah.
