طَاعَةٞ وَقَوۡلٞ مَّعۡرُوفٞۚ فَإِذَا عَزَمَ ٱلۡأَمۡرُ فَلَوۡ صَدَقُواْ ٱللَّهَ لَكَانَ خَيۡرٗا لَّهُمۡ ٢١
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.
Translation: Saheeh International (English)
Each word's meaning and sound
To follow Allah’s instruction and to utter fitting words that are not unseemly is better for them. When fighting is imposed and the matter becomes serious, if they are true to Allah, in their having faith in Him and following Him, it would be better for them than hypocrisy and going against Allah’s instructions.
