Musnad Abi Ya'la 5598 — the Messenger of Allah ﷺ performed ablution

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) performed ablution washing each part once, and said: "This is the ablution without which Allah Almighty does not accept the prayer." Then he (peace and blessings be upon him) performed ablution washing each part twice, and said: "This is moderation and balance in ablution; for such a person his reward is doubled." Then he (peace and blessings be upon him) performed ablution washing each part three times, and said: "This is my ablution, and the ablution of Allah's intimate friend Sayyiduna Ibrahim (peace be upon him) and of the other prophets before me, and this is the complete measure and obligation of ablution. So whoever performs ablution like this ablution of mine" Then he (peace and blessings be upon him) said that whoever says these words: 'Ashhadu an la ilaha illallahu wa ashhadu anna Muhammadan 'abduhu wa rasuluh' (I bear witness that there is none worthy of worship except Allah, and I bear witness that Muhammad (peace and blessings be upon him) is His servant and His Messenger), all eight gates of Paradise are opened for him, and he may enter through whichever of them he wishes.
