Surah Hud Verse 13 - English Translation by Aisha Bewley
Surah Hudأَمۡ يَقُولُونَ ٱفۡتَرَىٰهُۖ قُلۡ فَأۡتُواْ بِعَشۡرِ سُوَرٖ مِّثۡلِهِۦ مُفۡتَرَيَٰتٖ وَٱدۡعُواْ مَنِ ٱسۡتَطَعۡتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمۡ صَٰدِقِينَ
Or do they say, ´He has invented it?´ Say, ´Then produce ten invented suras like this, and call on anyone you can besides Allah if you are telling the truth.´
