The believers are only those who believe in Allah and His Messenger (24:62)

﴿إِنَّمَا الْمُؤْمِنُونَ الَّذِينَ آمَنُوا بِاللَّهِ وَرَسُولِهِ وَإِذَا كَانُوا مَعَهُ عَلَىٰ أَمْرٍ جَامِعٍ لَّمْ يَذْهَبُوا حَتَّىٰ يَسْتَأْذِنُوهُ ۚ إِنَّ الَّذِينَ يَسْتَأْذِنُونَكَ أُولَٰئِكَ الَّذِينَ يُؤْمِنُونَ بِاللَّهِ وَرَسُولِهِ ۚ فَإِذَا اسْتَأْذَنُوكَ لِبَعْضِ شَأْنِهِمْ فَأْذَن لِّمَن شِئْتَ مِنْهُمْ وَاسْتَغْفِرْ لَهُمُ اللَّهَ ۚ إِنَّ اللَّهَ غَفُورٌ رَّحِيمٌ﴾
[ النور: 62]

24:62 The believers are only those who believe in Allah and His Messenger and, when they are [meeting] with him for a matter of common interest, do not depart until they have asked his permission. Indeed, those who ask your permission, [O Muhammad] - those are the ones who believe in Allah and His Messenger. So when they ask your permission for something of their affairs, then give permission to whom you will among them and ask forgiveness for them of Allah. Indeed, Allah is Forgiving and Merciful.

The believers who are true in their faith are those who believe in Allah and His Messenger, and when they are summoned to convene by the Prophet peace be upon him for a matter in relation to the affairs of the Muslims, they do not leave until they seek his permission to do so.
O Messenger! Indeed, those who seek your permission before leaving, they are the ones who truly believe in Allah and His Messenger; so if they seek your permission to leave due to some important matter that concerns them, grant permission to whomsoever you wish from them and ask Allah to forgive their sins.
Indeed, Allah Forgiving of the sins of whoever repents from His servants, and is merciful to them.

The true believers are only those, who believe in (the Oneness of) Allah and His Messenger (Muhammad SAW), and when they are with him on some common matter, they go not away until they have asked his permission. Verily! Those who ask your permission, those are they who (really) believe in Allah and His Messenger. So if they ask your permission for some affairs of theirs, give permission to whom you will of them, and ask Allah for their forgiveness. Truly, Allah is Oft-Forgiving, Most Merciful.
