It is narrated from Hazrat Ibrahim bin Maisarah that he said: I asked Hazrat Tawus whether Umar bin Abdul Aziz was the Mahdi. He replied: He was indeed rightly guided (i.e., guided), but he was not the Mahdi, because when the Mahdi comes, the righteous person will be increased in righteousness, and the sinner will repent from sin. They will spend wealth, be strict with the officials, and show mercy to the poor.
