Jabir told that on the day of al-Hudaibiya the people were thirsty and God's messenger had in front of him a water-vessel from which he performed ablution. Then the people came forward to him and told him they had no water for ablution or for drinking except what was in his vessel; so, the Prophet put- his hand into the vessel and the water began to pour forth between his fingers like springs. Jabir said they drank and performed ablution, and when he was asked how many they were he replied that if they had been a hundred thousand it would have been sufficient for them, adding that they numbered fifteen hundred. (Bukhari and Muslim.)
