Jabir said: We came back to the (camp of the) army and Allah's Messenger (may peace be upon him) said: Jabir, call people for performing wudu. I cried: Come and perform wudu, come and perform wudu, come and perform wudu. I said: Allah's Messenger, there is not even a drop of water in the army camp, and there was a person who used to cool the water for Allah's Messenger (may peace be upon him) in the old water-skin which kept hanging by the twig. He asked me to go to such and such Ansari and ask him to see if there was any water in that skin. I went to him and cast a glance in it but did not find anything but a drop in the mouth of that water-skin and if I were to draw that, the water-skin's dried part would suck it up. I came to Allah's Messenger (may peace be upon him) and said: Allah's Messenger, I have not found anything in it but a drop of water in the mouth of the water-skin and now if I were to draw that, it would be absorbed. He said: Go and bring that to me. I brought that to him. He took hold of it and began to utter something which I could not understand and then pressed it with his hand and gave that to me and said: Jabir, announce for the tub to be brought. So I announced that the tub of the army (be brought). It was brought accordingly and I placed it before him (the Holy Prophet). Thereupon Allah's Messenger (may peace be upon him) placed his hands in the tub like this: with his fingers stretched out, and then he placed his fingers at the bottom of the tub and said: Jabir, take it (that waters-skin) and pour water over me, by reciting Bismillah, and I poured water and I said: Bismillah, and found water sprouting out between the fingers of Allah's Messenger (may peace be upon him). Then that tub gushed forth until it was filled up and the Messenger (may peace be upon him) said: Jabir, make an announcement to the effect: He who needs water should take that. Jabir said: The people came and got water until they were all satiated. I said: Is there anyone left who wants to get it? And Allah's Messenger (may peace be upon him) then lifted up his hand from that tub and it was still full.
