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."
The Saheeh International Quran Translation
وَأَقْسَمُوا۟ بِٱللَّهِ جَهْدَ أَيْمَٰنِهِمْ لَئِنْ أَمَرْتَهُمْ لَيَخْرُجُنَّ قُل لَّا تُقْسِمُوا۟ طَاعَةٌ مَّعْرُوفَةٌ إِنَّ ٱللَّهَ خَبِيرٌۢ بِمَا تَعْمَلُونَAnd 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."
