وَإِذَا تُتۡلَىٰ عَلَيۡهِمۡ ءَايَٰتُنَا قَالُواْ قَدۡ سَمِعۡنَا لَوۡ نَشَآءُ لَقُلۡنَا مِثۡلَ هَٰذَآ إِنۡ هَٰذَآ إِلَّآ أَسَٰطِيرُ ٱلۡأَوَّلِينَ٣١

wa-idhā tut'lā ʿalayhim āyātunā qālū qad samiʿ'nā law nashāu laqul'nā mith'la hādhā in hādhā illā asāṭīru l-awalīna

And when Our verses are recited to them, they say, "We have heard. If we willed, we could say [something] like this. This is not but legends of the former peoples."
