Surah An Najm Tafseer

That no burdened person shall bear the burden of another.

Meaning, every soul shall carry its own injustices, whether disbelief or sin, and none else shall carry its burden of sin, as Allah states

وَإِن تَدْعُ مُثْقَلَةٌ إِلَى حِمْلِهَا لَا يُحْمَلْ مِنْهُ شَىْءٌ وَلَوْ كَانَ ذَا قُرْبَى

And if one heavily laden calls another to (bear) his load, nothing of it will be lifted even though he be near of kin. (35:18)

Allah said,

وَأَن لَّيْسَ لِلْأِنسَانِ إِلاَّ مَا سَعَى
