The Ants
وَيَوْمَ يُنفَخُ فِى ٱلصُّورِ فَفَزِعَ مَن فِى ٱلسَّمَـٰوَٰتِ وَمَن فِى ٱلْأَرْضِ إِلَّا مَن شَآءَ ٱللَّهُ ۚ وَكُلٌّ أَتَوْهُ دَٰخِرِينَ
And [warn of] the Day the Horn will be blown, and whoever is in the heavens and whoever is on the earth will be terrified except whom Allah wills. And all will come to Him humbled.

وَوَقَعَ ٱلْقَوْلُ عَلَيْهِم بِمَا ظَلَمُوا۟ فَهُمْ لَا يَنطِقُونَ
And the decree will befall them for the wrong they did, and they will not [be able to] speak.
أَلَمْ يَرَوْا۟ أَنَّا جَعَلْنَا ٱلَّيْلَ لِيَسْكُنُوا۟ فِيهِ وَٱلنَّهَارَ مُبْصِرًا ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّقَوْمٍ يُؤْمِنُونَ
Do they not see that We made the night that they may rest therein and the day giving sight? Indeed in that are signs for a people who believe.
وَتَرَى ٱلْجِبَالَ تَحْسَبُهَا جَامِدَةً وَهِىَ تَمُرُّ مَرَّ ٱلسَّحَابِ ۚ صُنْعَ ٱللَّهِ ٱلَّذِىٓ أَتْقَنَ كُلَّ شَىْءٍ ۚ إِنَّهُۥ خَبِيرٌۢ بِمَا تَفْعَلُونَ
And you see the mountains, thinking them rigid, while they will pass as the passing of clouds. [It is] the work of Allah, who perfected all things. Indeed, He is Acquainted with that which you do.
مَن جَآءَ بِٱلْحَسَنَةِ فَلَهُۥ خَيْرٌ مِّنْهَا وَهُم مِّن فَزَعٍ يَوْمَئِذٍ ءَامِنُونَ
Whoever comes [at Judgement] with a good deed will have better than it, and they, from the terror of that Day, will be safe.
