8:32
وَإِذْ قَالُوا۟ ٱللَّهُمَّ إِن كَانَ هَـٰذَا هُوَ ٱلْحَقَّ مِنْ عِندِكَ فَأَمْطِرْ عَلَيْنَا حِجَارَةً مِّنَ ٱلسَّمَآءِ أَوِ ٱئْتِنَا بِعَذَابٍ أَلِيمٍ
wa-idh qālū l-lahuma in kāna hādhā huwa l-ḥaqa min ʿindika fa-amṭir ʿalaynā ḥijāratan mina l-samāi awi i'tinā biʿadhābin alīmin
They also said, ‘God, if this really is the truth from You, then rain stones on us from the heavens, or send us some other painful punishment.’
And (remember) when they said: "O Allâh! If this (the Qur’ân) is indeed the truth (revealed) from You, then rain down stones on us from the sky or bring on us a painful torment."
