قُلْ فَأْتُوا بِكِتَابٍ مِّنْ عِندِ اللَّهِ هُوَ أَهْدَى مِنْهُمَا أَتَّبِعْهُ إِن كُنتُمْ صَادِقِينَ
[28:49]
Say: Then bring some (other) book from Allah which is a better guide than both of them, (that) I may follow it, if you are truthful.
Say: "Then bring ye a Book from Allah, which is a better guide than either of them, that I may follow it! (do), if ye are truthful!"
Say (unto them, O Muhammad): Then bring a scripture from the presence of Allah that giveth clearer guidance than these two (that) I may follow it, if ye are truthful.
