The Calamity - 101:6 Whoever weighs heavily,
Those whose scales are heavy:
The Heights/7:8 On that Day the scales will be true. Those whose scales are heavy are those who have succeeded.
The Heights/7:9 And those whose scales are light are those who have lost their character by being unjust against Our signs.

The Calamity/101:5 And the mountains will be like discarded wool.

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.

The Shaking/99:7 Whoever does a single atom´s weight of good deeds will see it.
The Shaking/99:8 And whoever does an atom´s weight of evil will see it.
