Ibn Abbas RA reported: Messenger of Allah (sallallaahu alayhi wa sallam) said, “Do not drink in one gulp like a camel, but in two or three (gulps). Mention the Name of Allah (i.e.say Bismillah) when you start drinking and praise Him (i.e., say Al-hamdu lillah) after you have finished (drinking).”
(Tirmidhi)
