Musannaf Ibn Abi Shayba 1:406

Sharik narrated to us, from Khalid ibn Alqama, from Abd Khayr, from Ali, who said: He performed ablution, so he rinsed his mouth three times, and inhaled water into his nose three times from a single handful. He said: "This is the ablution of your Prophet, may Allah bless him and grant him peace."
