30:55
وَيَوْمَ تَقُومُ ٱلسَّاعَةُ يُقْسِمُ ٱلْمُجْرِمُونَ مَا لَبِثُوا۟ غَيْرَ سَاعَةٍ ۚ كَذَٰلِكَ كَانُوا۟ يُؤْفَكُونَ
And the Day the Hour appears the criminals will swear they had remained but an hour. Thus they were deluded.
The Romans

وَمَآ أَنتَ بِهَـٰدِ ٱلْعُمْىِ عَن ضَلَـٰلَتِهِمْ ۖ إِن تُسْمِعُ إِلَّا مَن يُؤْمِنُ بِـَٔايَـٰتِنَا فَهُم مُّسْلِمُونَ
And you cannot guide the blind away from their error. You will only make hear those who believe in Our verses so they are Muslims [in submission to Allah].
۞ ٱللَّهُ ٱلَّذِى خَلَقَكُم مِّن ضَعْفٍ ثُمَّ جَعَلَ مِنۢ بَعْدِ ضَعْفٍ قُوَّةً ثُمَّ جَعَلَ مِنۢ بَعْدِ قُوَّةٍ ضَعْفًا وَشَيْبَةً ۚ يَخْلُقُ مَا يَشَآءُ ۖ وَهُوَ ٱلْعَلِيمُ ٱلْقَدِيرُ
Allah is the one who created you from weakness, then made after weakness strength, then made after strength weakness and white hair. He creates what He wills, and He is the Knowing, the Competent.
وَقَالَ ٱلَّذِينَ أُوتُوا۟ ٱلْعِلْمَ وَٱلْإِيمَـٰنَ لَقَدْ لَبِثْتُمْ فِى كِتَـٰبِ ٱللَّهِ إِلَىٰ يَوْمِ ٱلْبَعْثِ ۖ فَهَـٰذَا يَوْمُ ٱلْبَعْثِ وَلَـٰكِنَّكُمْ كُنتُمْ لَا تَعْلَمُونَ
But those who were given knowledge and faith will say, "You remained the extent of Allah 's decree until the Day of Resurrection, and this is the Day of Resurrection, but you did not used to know."
فَيَوْمَئِذٍ لَّا يَنفَعُ ٱلَّذِينَ ظَلَمُوا۟ مَعْذِرَتُهُمْ وَلَا هُمْ يُسْتَعْتَبُونَ
So that Day, their excuse will not benefit those who wronged, nor will they be asked to appease [Allah].
