Ibn 'Abbas (May Allah be pleased with them) reported:
Messenger of Allah ﷺ 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)."

[At- Tirmidhi].

وعن ابن عباس رضى الله عنهما قال: قال رسول الله ﷺ: "لا تشربوا واحداً كشرب البعير، ولكن اشربوا مثنى وثلاث، وسموا إذا أنتم شربتم،واحمدوا إذا أنتم رفعتم" .
