Surah Ibrahim, ayah 9

أَلَمۡ يَأۡتِكُمۡ نَبَؤُاْ ٱلَّذِينَ مِن قَبۡلِكُمۡ قَوۡمِ نُوحٖ وَعَادٖ وَثَمُودَ وَٱلَّذِينَ مِنۢ بَعۡدِهِمۡ لَا يَعۡلَمُهُمۡ إِلَّا ٱللَّهُۚ جَآءَتۡهُمۡ رُسُلُهُم بِٱلۡبَيِّنَٰتِ فَرَدُّوٓاْ أَيۡدِيَهُمۡ فِيٓ أَفۡوَٰهِهِمۡ وَقَالُوٓاْ إِنَّا كَفَرۡنَا بِمَآ أُرۡسِلۡتُم بِهِۦ وَإِنَّا لَفِي شَكّٖ مِّمَّا تَدۡعُونَنَآ إِلَيۡهِ مُرِيبٖ ٩

Has there not reached you the news of those before you - the people of Noah and ʿAad and Thamūd and those after them? No one knows them [i.e., their number] but Allāh. Their messengers brought them clear proofs, but they returned their hands to their mouths⁶⁵¹ and said, "Indeed, we disbelieve in that with which you have been sent, and indeed we are, about that to which you invite us, in disquieting doubt."
