Musannaf Ibn Abi Shayba 1:2062

Waki’ narrated to us, from Shu’bah, who said: I asked al-Hakam, Hammad, and Qatadah about a man who forgets rinsing the mouth and sniffing water into the nose until he stands in the prayer. Al-Hakam and Qatadah said: He proceeds. And Hammad said: He departs [to repeat it].
