Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) asked for water and performed ablution once for each limb, then said: "This is the way of ablution; whoever does not perform ablution in this manner, his prayer is not accepted." Then he performed ablution twice for each limb and said: "This is the way of the person who performs ablution in this manner; Allah Almighty will grant him double the reward." Then he performed ablution three times for each limb and said: "This is my way and the way of the Prophets who came before me."
