Quran 47:21 from Surah Muhammad on Divine Marvels.
طَاعَةٞ وَقَوۡلٞ مَّعۡرُوفٞۚ فَإِذَا عَزَمَ ٱلۡأَمۡرُ فَلَوۡ صَدَقُواْ ٱللَّهَ لَكَانَ خَيۡرٗا لَّهُمۡ
English translation: (Is) obedience and a word kind And when (is) determined the matter then if they had been true (to) Allah surely it would have been better for them
Transliteration: ta'atun waqawlun ma'rufun fa-idha azama al-amru falaw sadaqu al-laha lakana khayran lahum
