What did the Prophet Muhammad (saw) do when water was scarce for the 'Asr prayer?
 Narrated Jabir bin `Abdullah:                     I was with the Prophet and the time for the `Asr prayer became due. We had no water with us except a little which was put in a vessel and was brought to the Prophet . He put his hand into it and spread out his fingers and then said, "Come along! Hurry up! All those who want to perform ablution. The blessing is from Allah.'' I saw the water gushing out from his fingers. So the people performed the ablution and drank, and I tried to drink more of that water (beyond my thirst and capacity), for I knew that it was a blessing. The sub-narrator said: I asked Jabir, "How many persons were you then?" He replied, "We were one-thousand four hundred men." Salim said: Jabir said, 1500.
