c)Jabir narrated that on the day of al-Hudaybiyah ... people came forward and told the Prophet that they had no water for wudu’ or drinking, except that which was in his vessel. The Prophet put his hand into the vessel and water began to pour forth between his fingers like springs ... He replied that if there were a hundred thousand it would be sufficient for them, adding that there were 1,500 (related by Bukhari and Muslim).
