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) said: "Whoever washes the limbs of wudu once, this is the obligatory (and compulsory) portion of wudu; whoever washes them twice, he will receive double the reward; and whoever washes them three times, this is my wudu and the wudu of the noble Prophets (peace be upon them) before me."
