Hud 11:13. Juz 12, page 223.
أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۖ قُلْ فَأْتُوا۟ بِعَشْرِ سُوَرٍ مِّثْلِهِۦ مُفْتَرَيَـٰتٍ وَٱدْعُوا۟ مَنِ ٱسْتَطَعْتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَـٰدِقِينَ١٣Or they say: He hath invented it. Say: Then bring ten surahs, the like thereof, invented, and call on everyone ye can beside Allah, if ye are truthful!
