Musannaf Ibn Abi Shayba 1:275

Ghundar narrated to us, from Shu'bah, from Abu Bishr, who said: I heard 'Umar al-'Anbari say that he saw 'Ubayd Allah ibn 'Abd Allah ibn 'Utbah, and he forgot to perform *istinshaq* (sniffing water into the nose). When the servant turned away with the pitcher, he said: "I forgot the command of the Messenger of Allah, may Allah bless him and grant him peace." So he called for water and performed *istinshaq* twice.
