AL ANFAAL — Ayat 31
وَإِذَا تُتْلَى عَلَيْهِمْ آيَاتُنَا قَالُواْ قَدْ سَمِعْنَا لَوْ نَشَاء لَقُلْنَا مِثْلَ هَـذَا إِنْ هَـذَا إِلاَّ أَسَاطِيرُ الأوَّلِينَ
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."
Tafsir Ibnu Katsir
وَإِذَا تُتْلَى عَلَيْهِمْ ءَايَـتُنَا قَالُواْ قَدْ سَمِعْنَا لَوْ نَشَآءُ لَقُلْنَا مِثْلَ هَـذَآ إِنْ هَـذَآ إِلاَّ أَسَـطِيرُ الأَوَّلِينَ - وَإِذْ قَالُواْ اللَّهُمَّ إِن كَانَ هَـذَا هُوَ الْحَقَّ مِنْ عِندِكَ فَأَمْطِرْ عَلَيْنَا حِجَارَةً مِّنَ السَّمَآءِ أَوِ ائْتِنَا بِعَذَابٍ أَلِيمٍ - وَمَا كَانَ اللَّهُ لِيُعَذِّبَهُمْ وَأَنتَ فِيهِمْ وَمَا كَانَ اللَّهُ مُعَذِّبَهُمْ وَهُمْ يَسْتَغْفِرُونَ
31. And when Our Ayat are recited to them, they say: â€We have heard (the Qur'an); if we wish we can say the like of this. This is nothing but the tales of the ancients.'' 32. And (remember) when they said: â€O Allah! If this (the Qur'an) is indeed the truth (revealed) from You, then rain down stones on us from the sky or bring on us a painful torment.'' 33. And Allah would not punish them while you (Muhammad ) are among them, nor will He punish them while they seek (Allah's) forgiveness.  Allah describes the disbelief, transgression, rebellion, as well as misguided statements that the pagans of Quraysh used to utter when they heard Allah's Ayat being recited to them,
