Al-Qalam - 68:7

إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِمَن ضَلَّ عَن سَبِيلِهِ وَهُوَ أَعْلَمُ بِالْمُهْتَدِينَ
[68:7]
Surely your Lord best knows him who errs from His way, and He best knows the followers of the right course.
Verily it is thy Lord that knoweth best, which (among men) hath strayed from His Path: and He knoweth best those who receive (true) Guidance.
Lo! thy Lord is Best Aware of him who strayeth from His way, and He is Best Aware of those who walk aright.
