Surah An-Noor Verse 51 - English Translation by A. J. Arberry
Surah An-Noorإِنَّمَا كَانَ قَوۡلَ ٱلۡمُؤۡمِنِينَ إِذَا دُعُوٓاْ إِلَى ٱللَّهِ وَرَسُولِهِۦ لِيَحۡكُمَ بَيۡنَهُمۡ أَن يَقُولُواْ سَمِعۡنَا وَأَطَعۡنَاۚ وَأُوْلَـٰٓئِكَ هُمُ ٱلۡمُفۡلِحُونَ
All that the believers say, when they are called to God and His Messenger, that he may judge between them, is that they say, 'We hear, and we obey'; those -- they are the prosperers
