Hazrat Ziyad bin Labeed narrates that the Messenger of Allah (peace and blessings be upon him) mentioned several tribulations: then he said: All this will happen when knowledge is taken away. The narrator says: I asked: O Messenger of Allah (peace and blessings be upon him)! How will knowledge be taken away when we recite the Qur'an and teach it to our children, and then they will teach it to their children, and thus this chain will continue until the Day of Judgment? He (peace and blessings be upon him) said: May your mother lose you, O Ziyad! I thought you were the most intelligent man in Madinah! Do not the Jews and Christians recite the Torah and the Gospel, yet they do not act upon the teachings found in them?
