وَإِذۡ قَالُواْ ٱللَّهُمَّ إِن كَانَ هَٰذَا هُوَ ٱلۡحَقَّ مِنۡ عِندِكَ فَأَمۡطِرۡ عَلَيۡنَا حِجَارَةً مِّنَ ٱلسَّمَآءِ أَوِ ٱئۡتِنَا بِعَذَابٍ أَلِيمٍ
Remember how they said: "O Allah if this is indeed the Truth from Thee, rain down on us a shower of stones form the sky, or send us a grievous penalty."<br/>
And when they said, 'O God! If this, that Muhammad may peace and salutation be upon him recites, be indeed the truth, revealed, from You, then rain down stones upon us from the sky, or bring on us a painful chastisement', in return for [our] denial of it: this was said by al-Nadr and others, in mockery and in delusion that he had some insight and certainty about it [Al-Qur'an] being false.
