Surah Al-Ahqaf — Ayah 19 (46:19)
وَلِكُلّٖ دَرَجَٰتٞ مِّمَّا عَمِلُواْۖ وَلِيُوَفِّيَهُمۡ أَعۡمَٰلَهُمۡ وَهُمۡ لَا يُظۡلَمُونَ ١٩
English translation (Saheeh International)
And for all there are degrees [of reward and punishment] for what they have done, and [it is] so that He may fully compensate them for their deeds, and they will not be wronged.
Brief commentary
And for each group - the group of Paradise and the group of the fire - are ranks according to their actions. The ranks of the people of Paradise are high ranks, whilst the ranks of the people of the fire are low ranks. And so that Allah gives them the full reward of their actions, and they will not be oppressed on the day of judgment by their good deeds being decreased or their bad deeds being increased.
