طَاعَةٞ وَقَوۡلٞ مَّعۡرُوفٞۚ فَإِذَا عَزَمَ ٱلۡأَمۡرُ فَلَوۡ صَدَقُواْ ٱللَّهَ لَكَانَ خَيۡرٗا لَّهُمۡ ٢١
Ṭāʿatuw wa qawlum maʿrūf, fa idhā ʿazamal-amru falaw ṣadaqullāha lakāna khayral lahum.
Obedience and good words. And when the matter [of fighting] was determined, if they had been true to Allāh, it would have been better for them.
