Sayyiduna Abu Layla (may Allah be pleased with him) narrates: We were with the Prophet (peace and blessings be upon him) on a military expedition, and we were struck by severe thirst. We complained about it to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) asked: "Does anyone have some leftover water in a waterskin?" A man brought a little water in a waterskin. The Prophet (peace and blessings be upon him) dug a hole in the ground and placed a leather mat over it, and he placed his palm on the ground. Then he said to the man with the waterskin: "Pour the water onto my palm and mention the name of Allah." He did so. Abu Layla (may Allah be pleased with him) said: I saw the water gushing forth from between the fingers of the Messenger of Allah (peace and blessings be upon him) until the people quenched their thirst and all of them drank.
