Has there not reached you the news of those before you - the people of Noah and 'Aad and Thamud and those after them? No one knows them but Allah. Their messengers brought them clear proofs, but they returned their hands to their mouths 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."  

أَلَمْ يَأْتِكُمْ نَبَأُ الَّذِينَ مِنْ قَبْلِكُمْ قَوْمِ نُوحٍ وَعَادٍ وَثَمُودَ ۛ وَالَّذِينَ مِنْ بَعْدِهِمْ ۛ لَا يَعْلَمُهُمْ إِلَّا اللَّهُ ۚ جَاءَتْهُمْ رُسُلُهُمْ بِالْبَيِّنَاتِ فَرَدُّوا أَيْدِيَهُمْ فِي أَفْوَاهِهِمْ وَقَالُوا إِنَّا كَفَرْنَا بِمَا أُرْسِلْتُمْ بِهِ وَإِنَّا لَفِي شَكٍّ مِمَّا تَدْعُونَنَا إِلَيْهِ مُرِيبٍ
