Quran 24:53 from Surah An-Noor on Divine Marvels.
۞وَأَقۡسَمُواْ بِٱللَّهِ جَهۡدَ أَيۡمَٰنِهِمۡ لَئِنۡ أَمَرۡتَهُمۡ لَيَخۡرُجُنَّۖ قُل لَّا تُقۡسِمُواْۖ طَاعَةٞ مَّعۡرُوفَةٌۚ إِنَّ ٱللَّهَ خَبِيرُۢ بِمَا تَعۡمَلُونَ
English translation: And they swear by Allah strong their oaths that if you ordered them surely they (would) go forth Say (Do) not swear Obedience (is) known Indeed Allah (is) All-Aware of what you do
