وَأَقْسَمُوا بِاللَّهِ جَهْدَ أَيْمَانِهِمْ لَئِنْ أَمَرْتَهُمْ لَيَخْرُجُنَّ ۖ قُلْ لَا تُقْسِمُوا ۖ طَاعَةٌ مَعْرُوفَةٌ ۚ إِنَّ اللَّهَ خَبِيرٌ بِمَا تَعْمَلُونَ

Surah An-Nur : 53
And they swear by Allah their strongest oaths that if you ordered them, they would go forth [in Allah 's cause]. Say, "Do not swear. [Such] obedience is known. Indeed, Allah is Acquainted with that which you do."
