Surah 24. An-Nur
Ayah 62
62إِنَّمَا ٱلْمُؤْمِنُونَ ٱلَّذِينَ ءَامَنُوا۟ بِٱللَّهِ وَرَسُولِهِۦ وَإِذَا كَانُوا۟ مَعَهُۥ عَلَىٰٓ أَمْرٍ جَامِعٍ لَّمْ يَذْهَبُوا۟ حَتَّىٰ يَسْتَـْٔذِنُوهُ ۚ إِنَّ ٱلَّذِينَ يَسْتَـْٔذِنُونَكَ أُو۟لَـٰٓئِكَ ٱلَّذِينَ يُؤْمِنُونَ بِٱللَّهِ وَرَسُولِهِۦ ۚ فَإِذَا ٱسْتَـْٔذَنُوكَ لِبَعْضِ شَأْنِهِمْ فَأْذَن لِّمَن شِئْتَ مِنْهُمْ وَٱسْتَغْفِرْ لَهُمُ ٱللَّهَ ۚ إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ
[62] True Believers97 are those who sincerely believe in Allah and His Messenger and who do not leave him without permission when they are with the Messenger for some common good;98 only those who ask your permission sincerely believe in Allah and His Messenger. Therefore, when they ask your permission for a private business,99 you may give permission to whomever you like,100 and ask Allah's forgiveness for such people.101 Allah is indeed Forgiving and Merciful.
97These are the final instructions being given to tighten the discipline of the Muslim Community and make it more organized than before.
98This Commandment is also applicable in respect of the successors of the Holy Prophet after him and other leaders of the Muslims. When the Muslims are called upon to get together for a common cause, whether relating to war or peace, it is not permissible for them to retreat or disperse without due permission of the leader.
99This contains a warning that it is absolutely unlawful to ask permission without any genuine need.
100That is, it depends upon the Prophet or his successor after him to grant or not to grant permission even in case of a genuine need. If he deems the collective cause to be more important than the individual need of the person, he may refuse permission, and a believer will not mind it.
101This again contains a warning: If in asking permission there is even a tinge of excuse making, or of placing individual interests above collective interests, it would be a sin. Therefore the Prophet or his successor should also pray for the forgiveness of the one whom he gives permission.
