Chapter: The drinking of milk with water
Narrated Jabir bin `Abdullah:
Allah's Messenger (ﷺ) and one of his companions entered upon an Ansari man and the Prophet (ﷺ) said to him, "If you have water kept overnight in a water skin, (give us), otherwise we will drink water by putting our mouth in it." The man was watering his garden then. He said, "O Allah's Messenger (ﷺ)! I have water kept overnight; let us go to the shade." So he took them both there and poured water into a bowl and milked a domestic goat of his in it. Allah's Messenger (ﷺ) drank, and then the man who had come along with him, drank.
