Musannaf Ibn Abi Shaybah 39298 — Reports on Abu Yaksum and the affair

It is narrated from Ubayd bin Umayr that when Allah Almighty intended to destroy the People of the Elephant, Allah Almighty sent against them birds that had been brought forth from the sea, resembling swallows. Each of these birds carried three stones of black and white: two stones in its feet and one stone in its beak. The narrator said: The birds came until they formed rows above the heads of the People of the Elephant. Then they cried out and threw down the stones that were in their claws and beaks. No stone fell on a man's head without coming out of his backside, and it did not strike any part of a man's body without coming out of the other side. The narrator said: Then Allah Almighty sent a violent wind, which struck the stones, and so their force increased. The narrator said: So all of those people were destroyed.
