Hadith 1442
Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: When the Prophet Muhammad (peace and blessings be upon him) came out after relieving himself, I and a boy from the Ansar would bring a vessel of water, and the Prophet Muhammad (peace and blessings be upon him) would perform istinja (cleaning) with it.
Hadith 1443
Lady Aisha (may Allah be pleased with her) said (to the women): Tell your husbands to perform istinja (cleaning) with water, because I feel shy to speak to them about this matter. The Prophet Muhammad (peace and blessings be upon him) used to do so.
