Abdullah bin Amr bin al-As (may Allah be pleased with him) narrated that I heard the Messenger of Allah (peace and blessings be upon him) say: "Allah will not take away knowledge by snatching it from the servants, but He will take away knowledge by causing the scholars to die. When no scholar remains, people will take ignorant ones as leaders; they will be asked questions and will give answers without knowledge. Thus, they will go astray themselves and will lead others astray as well."
