8:31

وَإِذَا تُتۡلَىٰ عَلَيۡهِمۡ ءَايَٰتُنَا قَالُواْ قَدۡ سَمِعۡنَا لَوۡ نَشَآءُ لَقُلۡنَا مِثۡلَ هَٰذَآ إِنۡ هَٰذَآ إِلَّآ أَسَٰطِيرُ ٱلۡأَوَّلِينَ ٣١

Wa idhā tutlā 'alayhim āyātunā qālū qad sami'nā law nashā'u laqulnā mithla hādhā in hādhā illā asātīrul-awwalīn

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."
