The Calamity - 101:11
It is a fiery fire!
In the context of verses 8, 9...11; Those whose scales are light; Those who deny the signs and miracles:
The Heights/7:8
On that Day the scales will be true. Those whose scales are heavy are those who have succeeded.
وَالْوَزْنُ يَوْمَئِذٍۨ الْحَقُّۚ فَمَنْ ثَقُلَتْ مَوَاز۪ينُهُ فَاُو۬لٰٓئِكَ هُمُ الْمُفْلِحُونَ
The Heights/7:9
And those whose scales are light are those who have lost their character by being unjust against Our signs.
وَمَنْ خَفَّتْ مَوَاز۪ينُهُ فَاُو۬لٰٓئِكَ الَّذ۪ينَ خَسِرُٓوا اَنْفُسَهُمْ بِمَا كَانُوا بِاٰيَاتِنَا يَظْلِمُونَ
The Prophets/21:47
We will set up scales of justice for the Day of Resurrection. No injustice will be done to anyone. We will take into account even the weight of a grain of mustard seed. We are sufficient as the reckoners.
وَنَضَعُ الْمَوَاز۪ينَ الْقِسْطَ لِيَوْمِ الْقِيٰمَةِ فَلَا تُظْلَمُ نَفْسٌ شَيْـٔاًۜ وَاِنْ كَانَ مِثْقَالَ حَبَّةٍ مِنْ خَرْدَلٍ اَتَيْنَا بِهَاۜ وَكَفٰى بِنَا حَاسِب۪ينَ
The Believers/23:103
As for those whose scales are light, they are the ones who will abide in Hell forever because they have caused themselves loss.
وَمَنْ خَفَّتْ مَوَاز۪ينُهُ فَاُو۬لٰٓئِكَ الَّذ۪ينَ خَسِرُٓوا اَنْفُسَهُمْ ف۪ي جَهَنَّمَ خَالِدُونَۚ
The Believers/23:104
The Fire will lick their faces while they are miserable therein.
تَلْفَحُ وُجُوهَهُمُ النَّارُ وَهُمْ ف۪يهَا كَالِحُونَ
The Believers/23:105
Were My Verses not recited to you and did you not deny them?
اَلَمْ تَكُنْ اٰيَات۪ي تُتْلٰى عَلَيْكُمْ فَكُنْتُمْ بِهَا تُكَذِّبُونَ
The Shaking/99:7
Whoever does a single atom´s weight of good deeds will see it.
فَمَنْ يَعْمَلْ مِثْقَالَ ذَرَّةٍ خَيْراً يَرَهُۜ
The Shaking/99:8
And whoever does an atom´s weight of evil will see it.
وَمَنْ يَعْمَلْ مِثْقَالَ ذَرَّةٍ شَراًّ يَرَهُ
The Calamity/101:5
And the mountains will be like discarded wool.
وَتَكُونُ الْجِبَالُ كَالْعِهْنِ الْمَنْفُوشِۜ
