Getting permission to the Prophet to leave his company

إِنَّمَا ٱلْمُؤْمِنُونَ ٱلَّذِينَ ءَامَنُوا۟ بِٱللَّهِ وَرَسُولِهِۦ وَإِذَا كَانُوا۟ مَعَهُۥ عَلَىٰٓ أَمْرٍۢ جَامِعٍۢ لَّمْ يَذْهَبُوا۟ حَتَّىٰ يَسْتَـْٔذِنُوهُ ۚ إِنَّ ٱلَّذِينَ يَسْتَـْٔذِنُونَكَ أُو۟لَٰٓئِكَ ٱلَّذِينَ يُؤْمِنُونَ بِٱللَّهِ وَرَسُولِهِۦ ۚ فَإِذَا ٱسْتَـْٔذَنُوكَ لِبَعْضِ شَأْنِهِمْ فَأْذَن لِّمَن شِئْتَ مِنْهُمْ وَٱسْتَغْفِرْ لَهُمُ ٱللَّهَ ۚ إِنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌۭ

Only those are believers, who believe in Allah and His Messenger: when they are with him on a matter requiring collective action, they do not depart until they have asked for his leave; those who ask for thy leave are those who believe in Allah and His Messenger; so when they ask for thy leave, for some business of theirs, give leave to those of them whom thou wilt, and ask Allah for their forgiveness: for Allah is Oft-Forgiving, Most Merciful.
