Sayyiduna Safwan bin Assal (may Allah be pleased with him) says: The Prophet (peace and blessings be upon him) encouraged acquiring knowledge before knowledge departs. A man said: "How will it depart, when we have learned it and taught it to our children?" The Prophet (peace and blessings be upon him) became angry, and he (peace and blessings be upon him) said: "Did the People of the Book not have the Torah and the Injil? Yet were they of any use to them?"
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Maslamah bin Ali al-Khushani, and he is da'if (weak).
