Al-Baqara 2:23

وَإِن كُنتُمْ فِى رَيْبٍۢ مِّمَّا نَزَّلْنَا عَلَىٰ عَبْدِنَا فَأْتُوا۟ بِسُورَةٍۢ مِّن مِّثْلِهِۦ وَٱدْعُوا۟ شُهَدَآءَكُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَٰدِقِينَ

Wa in kuntum fee raibim mimmaa nazzalnaa 'alaa 'abdinaa fatoo bi Sooratim mim mislihee wad'oo shuhadaaa'akum min doonil laahi in kuntum saadiqeen

And if you are in doubt as to that which We have revealed to Our servant, then produce a chapter like it and call on your witnesses besides Allah if you are truthful.
