Mawla Ibn Abbas, Imam Shu’bah says: When Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) performed the ghusl of janabah, he would pour water from his right hand onto his left hand and wash it seven times before putting it into the vessel. Once, he forgot how many times he had poured water on his hand, so he asked me: How many times did I pour water? I said: I do not know. He said: May you be bereft of your mother, why do you not know? Then he performed the ablution for prayer, then poured water over his head and body, and said: The Messenger of Allah (peace and blessings be upon him) used to perform ghusl in this manner.
