quran:24:51 –

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.  

All that the believers say, when they are summoned to God and His Messenger, that he may judge between them, is that they say, in other words, the saying that befits them is ˹to say˺: ‘We hear and we obey’, by responding ˹to the summons˺. And those, then, are the successful, the ones who will be saved.
القرآن:٢٤:٥١ –

إِنَّمَا كَانَ قَوْلَ الْمُؤْمِنِينَ إِذَا دُعُوا إِلَى اللَّهِ وَرَسُولِهِ لِيَحْكُمَ بَيْنَهُمْ أَنْ يَقُولُوا سَمِعْنَا وَأَطَعْنَا ۚ وَأُولَٰئِكَ هُمُ الْمُفْلِحُونَ  

{إنما كان قول المؤمنين إذا دعوا إلى الله ورسوله ليحكم بينهم} فالقول اللائق بهم {أن يقولوا سمعنا وأطعنا} بالإجابة {وأولئك} حينئذ {هم المفلحون} الناجون.
