Quran verses about Doubt

رَبَّنَآ إِنَّكَ جَامِعُ ٱلنَّاسِ لِيَوْمٍ لَّا رَيْبَ فِيهِ إِنَّ ٱللَّهَ لَا يُخْلِفُ ٱلْمِيعَادَ ۝٩

Our Lord, surely You will gather the people for a Day about which there is no doubt. Indeed, Allāh does not fail in His promise."

فَكَيْفَ إِذَا جَمَعْنَٰهُمْ لِيَوْمٍ لَّا رَيْبَ فِيهِ وَوُفِّيَتْ كُلُّ نَفْسٍ مَّا كَسَبَتْ وَهُمْ لَا يُظْلَمُونَ ۝٢٥

So how will it be when We assemble them for a Day about which there is no doubt? And each soul will be compensated [in full for] what it earned, and they will not be wronged.

ٱللَّهُ لَآ إِلَٰهَ إِلَّا هُوَ لَيَجْمَعَنَّكُمْ إِلَىٰ يَوْمِ ٱلْقِيَٰمَةِ لَا رَيْبَ فِيهِ وَمَنْ أَصْدَقُ مِنَ ٱللَّهِ حَدِيثًا ۝٨٧

Allāh - there is no deity except Him. He will surely assemble you for [account on] the Day of Resurrection, about which there is no doubt. And who is more truthful than Allāh in statement.

قُل لِّمَن مَّا فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ قُل لِّلَّهِ كَتَبَ عَلَىٰ نَفْسِهِ ٱلرَّحْمَةَ لَيَجْمَعَنَّكُمْ إِلَىٰ يَوْمِ ٱلْقِيَٰمَةِ لَا رَيْبَ فِيهِ ٱلَّذِينَ خَسِرُوٓا۟ أَنفُسَهُمْ فَهُمْ لَا يُؤْمِنُونَ ۝١٢

Say, "To whom belongs whatever is in the heavens and earth?" Say, "To Allāh." He has decreed upon Himself mercy. He will surely assemble you for the Day of Resurrection, about which there is no doubt. Those who will lose themselves [that Day] do not believe.

أَوَلَمْ يَرَوْا۟ أَنَّ ٱللَّهَ ٱلَّذِى خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ قَادِرٌ عَلَىٰٓ أَن يَخْلُقَ مِثْلَهُمْ وَجَعَلَ لَهُمْ أَجَلًا لَّا رَيْبَ فِيهِ فَأَبَى ٱلظَّٰلِمُونَ إِلَّا كُفُورًا ۝٩٩

Do they not see that Allāh, who created the heavens and earth, is [the one] Able to create the likes of them? And He has appointed for them a term, about which there is no doubt. But the wrongdoers refuse except disbelief.

وَكَذَٰلِكَ أَعْثَرْنَا عَلَيْهِمْ لِيَعْلَمُوٓا۟ أَنَّ وَعْدَ ٱللَّهِ حَقٌّ وَأَنَّ ٱلسَّاعَةَ لَا رَيْبَ فِيهَآ إِذْ يَتَنَٰزَعُونَ بَيْنَهُمْ أَمْرَهُمْ فَقَالُوا۟ ٱبْنُوا۟ عَلَيْهِم بُنْيَٰنًا رَّبُّهُمْ أَعْلَمُ بِهِمْ قَالَ ٱلَّذِينَ غَلَبُوا۟ عَلَىٰٓ أَمْرِهِمْ لَنَتَّخِذَنَّ عَلَيْهِم مَّسْجِدًا ۝٢١

And similarly, We caused them to be found that they [who found them] would know that the promise of Allāh is truth and that of the Hour there is no doubt. [That was] when they disputed among themselves about their affair and [then] said, "Construct over them a structure. Their Lord is most knowing about them." Said those who prevailed in the matter, "We will surely take [for ourselves] over them a masjid."

ذَٰلِكَ بِأَنَّ ٱللَّهَ هُوَ ٱلْحَقُّ وَأَنَّهُۥ يُحْىِ ٱلْمَوْتَىٰ وَأَنَّهُۥ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ ۝٦

That is because Allāh is the True Reality and because He gives life to the dead and because He is over all things competent
