19:39 وَأَنذِرْهُمْ يَوْمَ ٱلْحَسْرَةِ إِذْ قُضِىَ ٱلْأَمْرُ وَهُمْ فِى غَفْلَةٍ وَهُمْ لَا يُؤْمِنُونَ
And warn them of the day of intense regret, when the matter shall have been decided; and they are (now) in negligence and they do not believe.
Their reckoning has drawn near to men, and in heedlessness are they turning aside.
21:97 وَٱقْتَرَبَ ٱلْوَعْدُ ٱلْحَقُّ فَإِذَا هِىَ شَٰخِصَةٌ أَبْصَٰرُ ٱلَّذِينَ كَفَرُوا۟ يَٰوَيْلَنَا قَدْ كُنَّا فِى غَفْلَةٍ مِّنْ هَٰذَا بَلْ كُنَّا ظَٰلِمِينَ
And the true promise shall draw nigh, then lo! the eyes of those who disbelieved shall be fixedly open: O woe to us! surely we were m a state of heedlessness as to this; nay, we were unjust.
28:15 وَدَخَلَ ٱلْمَدِينَةَ عَلَىٰ حِينِ غَفْلَةٍ مِّنْ أَهْلِهَا فَوَجَدَ فِيهَا رَجُلَيْنِ يَقْتَتِلَانِ هَٰذَا مِن شِيعَتِهِۦ وَهَٰذَا مِنْ عَدُوِّهِۦ فَٱسْتَغَٰثَهُ ٱلَّذِى مِن شِيعَتِهِۦ عَلَى ٱلَّذِى مِنْ عَدُوِّهِۦ فَوَكَزَهُۥ مُوسَىٰ فَقَضَىٰ عَلَيْهِ قَالَ هَٰذَا مِنْ عَمَلِ ٱلشَّيْطَٰنِ إِنَّهُۥ عَدُوٌّ مُّضِلٌّ مُّبِينٌ
And he went into the city at a time of unvigilance on the part of its people, so he found therein two men fighting, one being of his party and the other of his foes, and he who was of his party cried out to him for help against him who was of his enemies, so Musa struck him with his fist and killed him. He said: This is on account of the Shaitan's doing; surely he is an enemy, openly leading astray.
50:22 لَّقَدْ كُنتَ فِى غَفْلَةٍ مِّنْ هَٰذَا فَكَشَفْنَا عَنكَ غِطَآءَكَ فَبَصَرُكَ ٱلْيَوْمَ حَدِيدٌ
Certainly you were heedless of it, but now We have removed from you your veil, so your sight today is sharp.
