قُلْ فَأْتُوا بِكِتَـٰبٍ مِّنْ عِندِ ٱللَّهِ هُوَ أَهْدَىٰ مِنْهُمَآ أَتَّبِعْهُ إِن كُنتُمْ صَـٰدِقِينَ

Qul fa/too bikitabin min AAindi Allahihuwa ahda minhuma attabiAAhu in kuntum sadiqeen

Say, "Then bring a scripture from Allāh which is more guiding than either of them that I may follow it, if you should be truthful."
