Surah An-Nur, Verse 51

إِنَّمَا كَانَ قَوۡلَ ٱلۡمُؤۡمِنِينَ إِذَا دُعُوٓاْ إِلَى ٱللَّهِ وَرَسُولِهِۦ لِيَحۡكُمَ بَيۡنَهُمۡ أَن يَقُولُواْ سَمِعۡنَا وَأَطَعۡنَاۚ وَأُوْلَٰٓئِكَ هُمُ ٱلۡمُفۡلِحُونَ٥١

innamā kāna qawla l-mu'minīna idhā duʿū ilā l-lahi warasūlihi liyaḥkuma baynahum an yaqūlū samiʿ'nā wa-aṭaʿnā wa-ulāika humu l-muf'liḥūna

The only statement of the [true] believers when they are called to Allāh and His Messenger to judge between them is that they say, "We hear and we obey." And those are the successful.
