It is narrated from Hazrat Ziyad bin Labeed (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) mentioned something and said that this will happen at the time when knowledge will be lost. We said, "O Messenger of Allah! (peace and blessings be upon him) We ourselves recite the Qur'an and teach it to our children, then they teach it to their children, and this chain will continue like this until the Day of Judgment, so how will knowledge be lost?" The Prophet (peace and blessings be upon him) said, "O Ibn Umm Labeed! May your mother lose you and weep for you! I thought you were one of the most intelligent men of Madinah. Do not the Jews and Christians recite the Torah and the Gospel? In reality, these people do not benefit from the teachings contained in them even a little."
