It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) went with his companion to the house of an Ansari and said: If you have water left over from the night in this vessel, (give it to us), otherwise we will drink directly (from the source). At that time, the man was watering his garden. He said to the Prophet (peace and blessings be upon him): I have water left over from the night, and he took both of them towards his tent. Upon reaching there, he poured water into a bowl and milked a goat over it, which the Prophet (peace and blessings be upon him) drank. After the Prophet (peace and blessings be upon him), he did the same for the companion who had come with him.
