سورة البقرة

وَإِنْ كُنْتُمْ فِي رَيْبٍ مِمَّا نَزَّلْنَا عَلَىٰ عَبْدِنَا فَأْتُوا بِسُورَةٍ مِنْ مِثْلِهِ وَادْعُوا شُهَدَاءَكُمْ مِنْ دُونِ اللَّهِ إِنْ كُنْتُمْ صَادِقِينَ ﴿٢٣﴾

Surah al-Baqarah

23. And if you are in doubt about what We have revealed to Our servant, then produce a chapter like it, and call your witnesses apart from Allah, if you are truthful.
