It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Do not drink in one breath like the camel; rather, drink in two or three breaths. Mention the name of Allah when you begin to drink, and praise Allah when you lift the vessel away."
