It is narrated from Sayyiduna Abbas (may Allah be pleased with him), he says: One night I was in the service of the Noble Prophet (peace and blessings be upon him), when he (peace and blessings be upon him) said: Do you see any star in the sky? I said: Yes. He (peace and blessings be upon him) said: What do you see? I said: I am seeing the Thurayya (Pleiades) stars. He (peace and blessings be upon him) said: From your progeny, in every era of tribulation, two men—equal to the number of the Thurayya stars—will rule over this Ummah.
