Qur'ān 24:51 · An-Nur (النور)

إِنَّمَا كَانَ قَوْلَ ٱلْمُؤْمِنِينَ إِذَا دُعُوٓا۟ إِلَى ٱللَّهِ وَرَسُولِهِۦ لِيَحْكُمَ بَيْنَهُمْ أَن يَقُولُوا۟ سَمِعْنَا وَأَطَعْنَا ۚ وَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ

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