Humran narrates that once I saw Sayyiduna Uthman (may Allah be pleased with him) performing ablution. He first poured water on both his hands, then washed both hands three times, then washed his face three times, rinsed his mouth and put water into his nose, washed his arms including the elbows three times, then wiped his head, and washed his feet including the ankles three times. He then said: I saw the Messenger of Allah (peace and blessings be upon him) performing ablution in this manner, after which the Prophet (peace and blessings be upon him) said: Whoever performs ablution like this of mine and then offers two units of prayer in such a way that he does not let thoughts and distractions enter his heart, Allah Almighty will forgive all his past sins.
