Mishkat al-Masabih 5902 — Excellent Qualities and Description of the Prophet

Anas said: The people were afflicted by famine in the time of God's messenger, and while the Prophet was preaching on a Friday a nomadic Arab got up and said, "The animals are perishing and the children are hungry, so make supplication to God for us." He then raised his hands, and we could not see a speck of cloud in the sky, but I swear by Him in whose hand my soul is that he had not lowered his hand before the clouds were appearing like mountains and before he descended from his pulpit, I saw the rain coming down on his beard. We had rain that day, the next, the following day, and on till the next Friday. Then that nomadic Arab or someone else got up and said, "Messenger of God, the buildings are being broken down and the animals are being drowned, so make supplication to God for us." He then raised his hands and said, "O God, round about us, but not on us." Then he did not point to any region in the clouds without their breaking up, and Medina became like a gap[*]. The wadi had a channel flowing in it for a month, and no one came from any region without speaking of plenty. In a version he said, "O God, round about us, but not on us; O God, on the mounds and knolls, in the basins of the wadis and in the plantations." He said: Then it stopped and we went out walking in the sun. *Meaning that Madina, unlike surrounding districts, had no clouds immediately above it or that it was like a wide, round hollow with the clouds round its edges. (Bukhari and Muslim.)
