Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) narrates: The Prophet Muhammad (peace and blessings be upon him) went to an Ansari's house. A companion was with him. The Prophet Muhammad (peace and blessings be upon him) and his companion greeted with salam. That person replied. He said: May my parents be sacrificed for you, the heat is intense. The Prophet Muhammad (peace and blessings be upon him) said to him: If you have such water that has been kept in a water-skin since last night, then give it to us to drink, otherwise we will drink the water (used for irrigating the field). That person was irrigating his garden at that time. He said: O Messenger of Allah (peace and blessings be upon him), I have such water that has been kept since last night. Then he went to the shelter, took both of them under it. He poured water from a water-skin, then milked his goat and presented it to the Prophet Muhammad (peace and blessings be upon him). The Prophet Muhammad (peace and blessings be upon him) drank it. Then he milked again, and the companion who had come with the Prophet Muhammad (peace and blessings be upon him) also drank it.
