Sayyiduna Ka'b (may Allah be pleased with him) said: Hold fast to the Qur'an, for it gives understanding to the intellect, it is the light of wisdom, the source of knowledge, and among the books that bring one close to Allah, it is the newest. In the Torah, Allah Almighty addressed (saying): O Muhammad! I am going to send down upon you the Torah as a new book, by which closed eyes, deaf ears, and hearts covered with heedless veils will be opened.
