Some etiquettes and injunctions in regard to meetings with the Holy Prophet ﷺ ' in particular, and in the society in general
The above verses contain two injunctions. The first injunction is that when the Holy Prophet ﷺ call people for the meeting in connection with jihad or any other religious matter, the demand of the faith is that all should attend and must not leave the meeting without his permission. If there is an emergency, permission may be sought from the Holy Prophet ﷺ ، who was advised that unless there is special need and requirement, permission may be granted on such requests. In the same connection those hypocrites are condemned who would come to attend the meeting only to fulfill the obligation of faith, but would quietly sneak out under the cover of some other person.
This verse was revealed at the time of the battle of Ahzab, when the Arab disbelievers and other groups joined together and suddenly attacked Madinah. After consultations with the companions, the Holy Prophet ﷺ consented to dig up a trench to defend against the attack. For this reason this battle is also known as 'the battle of trench (Khandaq) '. This battle was fought in Shawwal 5th Hijra. (Qurtubi)
Baihaqi and Ibn Ishaq have reported that the Holy Prophet ﷺ himself had taken part in the digging of the trench. But the hypocrites used to come late in the first place, and after doing a little bit of work just to show their presence, would sneak away quietly. As against this all the believers were putting in their best, and in case of any need or emergency would take permission from the Holy Prophet ﷺ before leaving the work. At that point this verse was revealed. (Mazhari)
A question and its answer
It appears from this verse that it is forbidden to get up and leave from the presence of the Holy Prophet ﷺ without seeking his permission. But there are several incidents when companions used to leave his meeting when they wished and would not deem it necessary to take his permission. The answer to this point is that the injunction mentioned in the present verse is not an injunction for ordinary meetings, but it is meant for specific gatherings, which the Holy Prophet ﷺ might have called for some need, as was the case at the time of battle of the trench.
The phrase ) عَلَىٰ أَمْرٍ جَامِعٍ (for a collective matter - 62) is itself pointing toward this exclusivity.
What does أَمْرٍ جَامِعٍ (collective matter) mean?
There are different views on this point. The most evident explanation is that this phrase is used for such acts for which the Holy Prophet ﷺ felt necessary to collect the people, as he regarded it important to collect the people for digging the trench on the occasion of battle of Ahzab. (Qurtubi - Mazhari)
Is this injunction exclusive to meetings of the Holy Prophet ﷺ or is general?
Since this injunction is issued for a religious and Islamic need, all the jurists agree that it is not exclusive to meetings of the Holy Prophet ﷺ . The same injunction would apply to any Imam or ruler of the Muslims who is in control of the government, if he called up a meeting. It is obligatory to attend the meetings called up by the rulers and it is not lawful to leave it without permission. (Qurtubi - Mazhari – Bayan ul-Quran)
This is but obvious that this injunction has greater stress and emphasis for meetings called up by the Holy Prophet ﷺ ، and its opposition is open callousness. As for the common meetings and gatherings (not convened by a ruler), acting upon this injunction is surely preferable and commendable from the point of view of Islamic social etiquette. When Muslims are gathered in a meeting for deliberation or action on a collective issue, one should Ie:av ( the meeting only after taking permission from the presiding person.
The second injunction
The second injunction is given in the last verse:
