Harzat Ali, Allah be pleased with him, relates that the Holy Prophet, peace and blessings of Allah be upon him, said:
“A time will come when nothing will remain of Islam except its name and nothing will remain of the Quran except its script. Mosques will be full of worshippers, but as far as righteousness is concerned, they will be empty and deserted. Their ulema [religious scholars] will be the worst of creatures under the canopy of the heavens. Evil plots will originate from them and to them will they return.”
(Mishkat)
