Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Bukhari :: Book 5 :: Volume 59 :: Hadith 473
Narrated Salim:
Jabir said "On the day of Al-Hudaibiya, the people felt thirsty and Allah's Apostle had a utensil containing water. He performer ablution from it and then the people came towards him. Allah's Apostle said, 'What is wrong with you?' The people said, 'O Allah's Apostle! We haven't got any water to perform ablution with or to drink, except what you have in your utensil.' So the Prophet put his hand in the utensil and the water started spouting out between his fingers like springs. So we drank and performed ablution." I said to Jabir, "What was your number on that day?" He replied, "Even if we had been one hundred thousand, that water would have been sufficient for us. Anyhow, we were 1500.'
