Abdullah bin Abi Awfa (may Allah be pleased with him) said: The Prophet (peace and blessings be upon him) was on a journey, and the people became thirsty, so he (peace and blessings be upon him) halted at a place. The Companions of the Prophet (peace and blessings be upon him) (may Allah be pleased with them) were saying: O Messenger of Allah (peace and blessings be upon him), drink! He (peace and blessings be upon him) said: "The one who gives the people to drink drinks last of all."
