قَدْ عَلِمْنَا مَا تَنقُصُ الْأَرْضُ مِنْهُمْ وَعِندَنَا كِتَابٌ حَفِيظٌ
We know what the earth diminishes from them, and with Us is a preserving Book.
Agha Ali Puya Commentary
Commentary on Quran 50:4
[Pooya/Ali Commentary 50:4] The earth only turns the bodies into dust, but it has no power over the soul. The full account of the soul's activities is in the preserved tablet (lawh makfuz); see commentary of Zukhruf: 4.
