(The people of the Scripture ask of thee that thou shouldst cause an (actual) Book to descend upon them from heaven…) [4:153].
This was revealed about the Jews. They said to the Prophet, Allah bless him and give him peace: “If you are truly a prophet, bring us an actual Book from heaven as Moses did”, and so this verse was revealed.
