Humran bin Aban (may Allah have mercy on him) narrates that I saw Sayyiduna Uthman (may Allah be pleased with him) performing ablution. He poured water on his hands and washed them three times, then rinsed his mouth three times and sniffed water into his nose and blew it out, then washed his face three times, then washed his right hand up to the elbow three times, then washed his left hand in the same way, wiped his head, washed his right foot up to the ankle three times, and washed his left foot in the same way. Then he said: I saw the Messenger of Allah (peace and blessings be upon him) performing ablution like mine, and after performing ablution like mine, he said: Whoever performs ablution like mine, then offers two rak‘ahs (prayer of greeting the ablution) without being distracted by worldly thoughts, all his previous sins will be forgiven.
