What is the story of the person that came to the mosque on the Friday prayer and requested the Prophet Muhammad (saw) to make dua for rain?
 Anas b. Malik reported that a person entered the mosque through the door situated on theside of Daral-Qada' during Friday (prayer) and the messenger of Allah (may peace be upon him) was delivering the sermon while standing. He came and stood in front of the Messenger of Allah (may peace be upon him) and said:                      Messenger of Allah, the camels died and the passages were blocked; so supplicate Allah to send down rain upon us. The Messenger of Allah (may peace be upon him) raised his hands and then said: (O Allah, send down rain upon us; O Allah, send dowp rain upon us; O Allah, send down rain upon us. Anas said: By Allah, we did not see any cloud or any patch of it, and there was neither any house or building standing between us and the (hillock) Sal'a. There appeared a cloud in the shape of a shield from behind it, and as it (came high) in the sky it spread and then there was a downpour of rain. By Allah, we did not see the sun throughout the week. Then (that very man) came on the coming Friday through the same door when the Messenger of Allah (may peace be upon him) was standing and delivering the sermon. He stood in front of him and said: Messenger of Allah, our animals died and the passages blocked. Supplicate Allah to stop the rain for us. The Messenger of Allah (may peace be upon him) again raised his hands and said: O Allah, let it (rain) fall in our suburbs and not on us, O Allah (send it down) on the hillocks and small mountains and the river-beds and at places where trees grow. The rain stopped, and as we stepped out we were walking in sun- shine. He (the narrator) said to Sharik: I asked Anas b. Malik if he was the same man. He said: I do not know.
