It is narrated from Sayyiduna ‘Ubādah bin Sāmit (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said:“After me, soon there will be rulers appointed over you who will introduce among you things (evil) which you will disapprove of, and they will reject things (good) which you recognize (as virtue). If anyone lives to see such a time, (let him remember that) there is no obedience to such (rulers) who disobey Allah, the Exalted.”
