Sahih Muslim — The Book of Prayer - Rain — Hadith No: 2081

Humran, the freed slave of 'Uthman said:I saw Uthman call for a vessel (of water) and poured water over his hands three times and then washed them. Then he put his right hand in the vessel and rinsed his mouth and cleaned his nose. Then he washed his face three times and his hands up to the elbow three times; then wiped his head, then washed his feet three times. Then he said that the Messenger of Allah (ﷺ) had said: He who performed ablution like this ablution of mine and offered two raka`ahs of prayer without allowing his thoughts to be distracted, all his previous sins would be expiated

Abu Huraira reported Allah's Apostle (ﷺ) as saying:When anyone wipes himself with pebbles (after answering the call of nature) he must make use of an odd number and when any one of you performs ablution he must snuff in his nose water and then clean it

Nu'aim b. 'Abdallah reported:He saw Abu Huraira perform ablution. He washed his face and washed his hands up to the arms. He then washed his feet and reached up to the shanks and then said: I heard Allah's Messenger (ﷺ) say: My people would come with bright faces and bright hands and feet on account of the marks of ablution, so he who can increase the lustre of his forehead (and that of his hands and legs) should do so

Miqdam b. Shuraih narrated it from his father who said:I asked A'isha what Allah's Apostle (ﷺ) did first when he entered his house, and she replied: He used tooth-stick (first of all)
