Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Bara bin Azib that when we camped on the day of Hudaybiyyah, we found its well in such a state that those before us had already drunk from it. Then the Prophet (peace and blessings be upon him) sat on the edge of the well, and he asked for a bucket of water from it. He took some of that water into his blessed mouth and then rinsed it back into the bucket, and prayed to Allah. Then the water of that well increased so much that all the people were able to drink their fill from it.
