Sura Muḥammad 47:21

طَاعَةٌ وَقَوْلٌ مَّعْرُوفٌ فَإِذَا عَزَمَ ٱلْأَمْرُ فَلَوْ صَدَقُوا۟ ٱللَّـهَ لَكَانَ خَيْرًا لَّهُمْ

ṭāʿatun wa-qawlun maʿrūfun fa-idhā ʿazama l-amru fa-law ṣadaqū allāha la-kāna khayran lahum

Were it to obey and say what is just, and when a matter is resolved on, it were best for them if they were true to Allah.
