Quran 21:47 — The Prophets (Al-Anbya')

We will establish the scales of justice on the Day of Resurrection. No soul will suffer the least injustice. Even the equivalent of a mustard seed will be accounted for. We are the most efficient reckoners.

[21:46] When a sample of your Lord's retribution afflicts them, they readily say, "We were indeed wicked."

[21:48] We gave Moses and Aaron the Statute Book, a beacon, and a reminder for the righteous.
