Mishkat al-Masabih

Al-Bara' b. `Azib said:On the day of al-Hudaibiya we were along with God's messenger to the number of fourteen hundred. Now al Hudaibiya was a well which we drained leaving not a drop in it, and when the Prophet heard of that he came to it and sat down beside it. He called for a vessel of water, and when he had performed ablution, rinsed his mouth and made supplication, he poured the water into it, and told them to leave it for a time. Then they drew sufficient water for themselves and their animals until they left. Bukhari transmitted it.
