وَقَالَ ٱلَّذِينَ لَا يَعْلَمُونَ لَوْلَا يُكَلِّمُنَا ٱللَّهُ أَوْ تَأْتِينَآ ءَايَةٌ ۗ كَذَٰلِكَ قَالَ ٱلَّذِينَ مِن قَبْلِهِم مِّثْلَ قَوْلِهِمْ ۘ تَشَـٰبَهَتْ قُلُوبُهُمْ ۗ قَدْ بَيَّنَّا ٱلْـَٔايَـٰتِ لِقَوْمٍ يُوقِنُونَ

Those who do not know say, "Why does Allāh not speak to us or there come to us a sign?" Thus spoke those before them like their words. Their hearts resemble each other. We have shown clearly the signs to a people who are certain [in faith].

Al-Baqarah 118

وَإِن كُنتُمْ فِى رَيْبٍ مِّمَّا نَزَّلْنَا عَلَىٰ عَبْدِنَا فَأْتُوا۟ بِسُورَةٍ مِّن مِّثْلِهِۦ وَٱدْعُوا۟ شُهَدَآءَكُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَـٰدِقِينَ

And if you are in doubt about what We have sent down [i.e., the Qur’ān] upon Our Servant [i.e., Prophet Muḥammad (ﷺ)], then produce a sūrah the like thereof and call upon your witnesses [i.e., supporters] other than Allāh, if you should be truthful.

Al-Baqarah 23

فَقَالَ ٱلْمَلَأُ ٱلَّذِينَ كَفَرُوا۟ مِن قَوْمِهِۦ مَا نَرَىٰكَ إِلَّا بَشَرًا مِّثْلَنَا وَمَا نَرَىٰكَ ٱتَّبَعَكَ إِلَّا ٱلَّذِينَ هُمْ أَرَاذِلُنَا بَادِىَ ٱلرَّأْىِ وَمَا نَرَىٰ لَكُمْ عَلَيْنَا مِن فَضْلٍۭ بَلْ نَظُنُّكُمْ كَـٰذِبِينَ

So the eminent among those who disbelieved from his people said, "We do not see you but as a man like ourselves, and we do not see you followed except by those who are the lowest of us [and] at first suggestion.1 And we do not see in you over us any merit; rather, we think you are liars."

Hud 27

۞ قَالَتْ رُسُلُهُمْ أَفِى ٱللَّهِ شَكٌّ فَاطِرِ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۖ يَدْعُوكُمْ لِيَغْفِرَ لَكُم مِّن ذُنُوبِكُمْ وَيُؤَخِّرَكُمْ إِلَىٰٓ أَجَلٍ مُّسَمًّى ۚ قَالُوٓا۟ إِنْ أَنتُمْ إِلَّا بَشَرٌ مِّثْلُنَا تُرِيدُونَ أَن تَصُدُّونَا عَمَّا كَانَ يَعْبُدُ ءَابَآؤُنَا فَأْتُونَا بِسُلْطَـٰنٍ مُّبِينٍ

Their messengers said, "Can there be doubt about Allāh, Creator of the heavens and earth? He invites you that He may forgive you of your sins, and He delays you [i.e., your death] for a specified term." They said, "You are not but men like us who wish to avert us from what our fathers were worshipping. So bring us a clear authority [i.e., evidence]."

Ibrahim 10

أَلَمْ يَأْتِكُمْ نَبَؤُا۟ ٱلَّذِينَ مِن قَبْلِكُمْ قَوْمِ نُوحٍ وَعَادٍ وَثَمُودَ ۛ وَٱلَّذِينَ مِنۢ بَعْدِهِمْ ۛ لَا يَعْلَمُهُمْ إِلَّا ٱللَّهُ ۚ جَآءَتْهُمْ رُسُلُهُم بِٱلْبَيِّنَـٰتِ فَرَدُّوٓا۟ أَيْدِيَهُمْ فِىٓ أَفْوَٰهِهِمْ وَقَالُوٓا۟ إِنَّا كَفَرْنَا بِمَآ أُرْسِلْتُم بِهِۦ وَإِنَّا لَفِى شَكٍّ مِّمَّا تَدْعُونَنَآ إِلَيْهِ مُرِيبٍ

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 mouths1 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."

Ibrahim 9
