It is narrated from Abdullah bin Umar that he said: The Messenger of Allah, peace and blessings be upon him, said: Verily, Allah will not take away knowledge by snatching it from the people, but He will take away knowledge by taking away the scholars (from the world), until when no scholar remains, people will take the ignorant as their leaders. They will be asked (about religious matters), and they will give verdicts without knowledge. Thus, they will go astray themselves and will lead others astray as well.
