23وَإِن كُنتُم في رَيبٍ مِمّا نَزَّلنا عَلىٰ عَبدِنا فَأتوا بِسورَةٍ مِن مِثلِهِ وَادعوا شُهَداءَكُم مِن دونِ اللَّهِ إِن كُنتُم صادِقينَT. B. IrvingIf you (all) are in any doubt about what We have sent down to Our servant, then bring a chapter like it and call in your witnesses besides God if you are so truthful.
