The Prophet (may Allah’s peace and blessings be upon him) performed ablution by washing the body parts once.

"If any of you wakes up from his sleep, let him blow water out of his nose three times, as the devil spends the night on his nostrils."

We returned with the Messenger of Allah (may Allah's peace and blessings be upon him) from Makkah to Madīnah, and when we came to some water on the way, some of the people were in a hurry at the time of the ‘Asr prayer and performed ablution hurriedly; and when we reached them, their heels were dry, and no water had touched them. Thereupon, the Messenger of Allah (may Allah's peace and blessings be upon him) said: "Beware of negnot washing your heels properly, for not doing so can lead to them being burnt in the Hellfire! So, perform your ablution thoroughly."

Humrān, the freed slave of 'Uthmān ibn' Affān, reported that he saw 'Uthmān ibn' Affān asking (for water) to perform ablution, and he poured water from his vessel over his hands and washed them thrice and then put his right hand in the water and rinsed his mouth and washed his nose by putting water in it and then blowing it out. Then, he washed his face thrice and his forearms up to the elbows thrice. Then, he passed his wet hands over his head and washed each foot thrice. After that, he said: "I saw the Prophet (may Allah's peace and blessings be upon him) perform ablution like this ablution of mine, and he said: 'If anyone performs ablution like this ablution of mine and offers two Rak'ahs during which he does not think of anything else, Allah will forgive his past sins.'"

The Prophet (may Allah’s peace and blessings be upon him) performed ablution by washing the body parts twice.

I witnessed 'Amr ibn Abi Hasan asking 'Abdullah ibn Zayd about the ablution of the Prophet (may Allah's peace and blessings be upon him), so he asked for a vessel of water and performed ablution like that of the Prophet (may Allah's peace and blessings be upon him) in front of them. He poured water from the vessel on his hand, washing his hands thrice. Then, he put his hand inside the vessel, rinsed his mouth, sniffed water, and blew it out with three handfuls. He put his hand in the water again and washed his face thrice. Then, he washed his hands twice up to the elbows, after which he put his hand in the water and wiped over his head, bringing them to the front and the back of his head once. Then, he washed his feet up to the ankles.
