Quran 24:53 An-Nur, ayah 53 of 64

۞ وَأَقْسَمُوا۟ بِٱللَّهِ جَهْدَ أَيْمَـٰنِهِمْ لَئِنْ أَمَرْتَهُمْ لَيَخْرُجُنَّ ۖ قُل لَّا تُقْسِمُوا۟ ۖ طَاعَةٌ مَّعْرُوفَةٌ ۚ إِنَّ ٱللَّهَ خَبِيرٌۢ بِمَا تَعْمَلُونَ ۝٥٣

24:53 They swear by Allah solemnly that, if thou order them, they will go forth. Say: Swear not; known obedience (is better). Lo! Allah is Informed of what ye do.
