Musannaf Ibn Abi Shaybah 40432 — Reports on the tribulation

It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Among my nation there will be the Mahdi. Whether his life is long or short, he will rule over the earth for seven years, or eight years, or nine years. He will fill the earth with justice and fairness just as it had been filled with tyranny. Then rain will descend from the sky and the earth will bring forth its blessing." He (peace and blessings be upon him) said: "My nation will live in his time a life such as it had never lived before."
