Surat Al Anfal: (31-32)

{وَإِذَا تُتْلَى عَلَيْهِمْ آيَاتُنَا قَالُواْ قَدْ سَمِعْنَا لَوْ نَشَاء لَقُلْنَا مِثْلَ هَـذَا إِنْ هَـذَا إِلاَّ أَسَاطِيرُ الأوَّلِينَ} [الأنفال: 31]

31- When the Ayahs of the Glorious Qur'an are recited to them, they show stubbornness and say in haughtiness: We have heard what you had said, O Muhammad and if we willed, we would say similar words. These are just the news and stories of the past nations, not the words of Allah.

{وَإِذْ قَالُواْ اللَّهُمَّ إِن كَانَ هَـذَا هُوَ الْحَقَّ مِنْ عِندِكَ فَأَمْطِرْ عَلَيْنَا حِجَارَةً مِّنَ السَّمَاءِ أَوِ ائْتِنَا بِعَذَابٍ أَلِيمٍ} [الأنفال: 32]

32- They said while they are in the darkness of disbelief and polytheism out of their belying and denial: O Allah, if what Muhammad brought us was the truth which You sent down, punish us by sending stones upon us from the sky or take us by a severe and painful torment.
