Sahih Bukhari | Volume 7 | Hadith Number 517

Narrated by Jabir bin 'Abdullah
Allah's Apostle and one of his companions entered upon an Ansari man and the Prophet 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 Apostle! 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 Apostle drank, and then the man who had come along with him, drank.
