An Nur, 51 Ayah
24:51
إِنَّمَا كَانَ قَوۡلَ ٱلۡمُؤۡمِنِينَ إِذَا دُعُوٓاْ إِلَى ٱللَّهِ وَرَسُولِهِۦ لِيَحۡكُمَ بَيۡنَهُمۡ أَن يَقُولُواْ سَمِعۡنَا وَأَطَعۡنَاۚ وَأُوْلَٰٓئِكَ هُمُ ٱلۡمُفۡلِحُونَ ٥١
'Innamā Kāna Qawla Al-Mu'uminīna 'Idhā Du`ū 'Ilá Al-Lahi Wa Rasūlihi Liyaĥkuma Baynahum 'An Yaqūlū Sami`nā Wa 'Aţa`nā ۚ Wa 'Ūlā'ika Humu Al-Mufliĥūna
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.
