The Cattle
وَلَوْ تَرَىٰٓ إِذْ وُقِفُوا۟ عَلَىٰ رَبِّهِمْ ۚ قَالَ أَلَيْسَ هَـٰذَا بِٱلْحَقِّ ۚ قَالُوا۟ بَلَىٰ وَرَبِّنَا ۚ قَالَ فَذُوقُوا۟ ٱلْعَذَابَ بِمَا كُنتُمْ تَكْفُرُونَ
If you could but see when they will be made to stand before their Lord. He will say, "Is this not the truth?" They will say, "Yes, by our Lord." He will [then] say, "So taste the punishment because you used to disbelieve."

بَلْ بَدَا لَهُم مَّا كَانُوا۟ يُخْفُونَ مِن قَبْلُ ۖ وَلَوْ رُدُّوا۟ لَعَادُوا۟ لِمَا نُهُوا۟ عَنْهُ وَإِنَّهُمْ لَكَـٰذِبُونَ
But what they concealed before has [now] appeared to them. And even if they were returned, they would return to that which they were forbidden; and indeed, they are liars.
وَقَالُوٓا۟ إِنْ هِىَ إِلَّا حَيَاتُنَا ٱلدُّنْيَا وَمَا نَحْنُ بِمَبْعُوثِينَ
And they say, "There is none but our worldly life, and we will not be resurrected."
قَدْ خَسِرَ ٱلَّذِينَ كَذَّبُوا۟ بِلِقَآءِ ٱللَّهِ ۖ حَتَّىٰٓ إِذَا جَآءَتْهُمُ ٱلسَّاعَةُ بَغْتَةً قَالُوا۟ يَـٰحَسْرَتَنَا عَلَىٰ مَا فَرَّطْنَا فِيهَا وَهُمْ يَحْمِلُونَ أَوْزَارَهُمْ عَلَىٰ ظُهُورِهِمْ ۚ أَلَا سَآءَ مَا يَزِرُونَ
Those will have lost who deny the meeting with Allah, until when the Hour [of resurrection] comes upon them unexpectedly, they will say, "Oh, [how great is] our regret over what we neglected concerning it," while they bear their burdens on their backs. Unquestionably, evil is that which they bear.
وَمَا ٱلْحَيَوٰةُ ٱلدُّنْيَآ إِلَّا لَعِبٌ وَلَهْوٌ ۖ وَلَلدَّارُ ٱلْـَٔاخِرَةُ خَيْرٌ لِّلَّذِينَ يَتَّقُونَ ۗ أَفَلَا تَعْقِلُونَ
And the worldly life is not but amusement and diversion; but the home of the Hereafter is best for those who fear Allah, so will you not reason?
