49قُل فَأتوا بِكِتابٍ مِن عِندِ اللَّهِ هُوَ أَهدىٰ مِنهُما أَتَّبِعهُ إِن كُنتُم صادِقينَMuhammad AsadSay: "Produce, then, [another] revelation from God which would offer better guidance than either of these two1 - [and] I shall follow it, if you speak the truth!"I.e., the Torah and the Qur'an. The Gospel is not mentioned in this context because, as Jesus himself had stressed, his message was based on the Law of Moses, and was not meant to displace the latter.
