فَلَا تُظْلَمُ نَفْسٌ شَيْئًا
“No soul will be wronged in the least.”
Lā negates the statement. Tuẓlamu is passive: “will be wronged,” and nafsun means a soul or person. Shayʾan reinforces the breadth of the negation—nothing at all.
وَكَفَى بِنَا حَاسِبِينَ
“Allah is sufficient as Reckoner.”
The grammatical details help the learner notice the force of the statement, but the central point remains that no person's right will be overlooked.
