Surah An-Najm — Ayah 30 (53:30)
ذَٰلِكَ مَبۡلَغُهُم مِّنَ ٱلۡعِلۡمِۚ إِنَّ رَبَّكَ هُوَ أَعۡلَمُ بِمَن ضَلَّ عَن سَبِيلِهِۦ وَهُوَ أَعۡلَمُ بِمَنِ ٱهۡتَدَىٰ ٣٠
English translation (Saheeh International)
That is their sum of knowledge. Indeed, your Lord is most knowing of who strays from His way, and He is most knowing of who is guided.
Brief commentary
That which the idolaters say - about giving the angels female names - is the limit of their knowledge because they are ignorant. They have not reached certainty. Your Lord - O Messenger- knows best about those who deviate from the path of truth and He knows best about those who are guided to its path. Nothing of that is hidden from Him.
