﴿ ۞ وَأَقْسَمُوا۟ بِٱللَّهِ جَهْدَ أَيْمَٰنِهِمْ لَئِنْ أَمَرْتَهُمْ لَيَخْرُجُنَّ ۖ قُل لَّا تُقْسِمُوا۟ ۖ طَاعَةٌۭ مَّعْرُوفَةٌ ۚ إِنَّ ٱللَّهَ خَبِيرٌۢ بِمَا تَعْمَلُونَ ﴾

“Now [as for those half-hearted ones,] they do swear by God with their most solemn oaths that if thou [O Apostle] shouldst ever bid them to do so, they would most certainly go forth [and sacrifice themselves]. Say: “Swear not! Reasonable compliance [with God’s message is all that is required of you]. Verily, God is aware of all that you do!””
