‘Ali reported God’s messenger as saying, “ A time is soon coming to
mankind when nothing of Islam but its name will remain and only the
written form of the Qur’an will remain. Their mosques will be in fine
condition but will be devoid of guidance, their learned men will be the
worst people under heaven, corruption coming forth from them and
returning among them.” Baihaqi transmitted it in Shu'ab al-iman.
