أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۖ قُلْ فَأْتُوا۟ بِعَشْرِ سُوَرٍ مِّثْلِهِۦ مُفْتَرَيَـٰتٍ وَٱدْعُوا۟ مَنِ ٱسْتَطَعْتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَـٰدِقِينَ
Am yaqooloonaf taraahu qul faatoo bi'ashri Suwarim mislihee muftarayaatinw wad'oo manis tata'tum min doonil laahi in kuntum saadiqeen
Or do they say, "He has invented it"? Say, "Then bring ten suras like it, invented, and call on whomever you can besides God, if you are truthful."
