Al Anfal Ayah 31

وَإِذَا تُتْلَىٰ عَلَيْهِمْ ءَايَـٰتُنَا قَالُواْ قَدْ سَمِعْنَا لَوْ نَشَآءُ لَقُلْنَا مِثْلَ هَـٰذَآ‌ۙ إِنْ هَـٰذَآ إِلَّآ أَسَـٰطِيرُ ٱلْأَوَّلِينَ ٣١ Whenever Our revelations are recited to them, they challenge ?you?, “We have already heard ?the recitation?. If we wanted, we could have easily produced something similar. This ?Quran? is nothing but ancient fables!”
