Quran 53:30 — The Stars (Al-Najm)

ذٰلِكَ مَبلَغُهُم مِنَ العِلمِ ۚ إِنَّ رَبَّكَ هُوَ أَعلَمُ بِمَن ضَلَّ عَن سَبيلِهِ وَهُوَ أَعلَمُ بِمَنِ اهتَدىٰ

This is the extent of their knowledge. Your Lord is fully aware of those who strayed away from His path, and He is fully aware of those who are guided.

[53:29] You shall disregard those who turn away from our message, and become preoccupied with this worldly life.

[53:31] To GOD belongs everything in the heavens and everything on earth. He will requite those who commit evil for their works, and will reward the righteous for their righteousness.
