Musnad Ahmad 26:242

Sulayman ibn Dawud al-Hashimi narrated to us, Isma'il informed us, 'Amr—meaning Ibn Abi 'Amr—informed me, from 'Ubayd Allah and Hamzah, the two sons of 'Abd Allah ibn 'Utbah, from 'Abd Allah ibn Mas'ud, that the Prophet, peace and blessings of Allah be upon him, used to eat meat, then stand for prayer, and he would not touch water.
