In The Name of Allah, The Most Merciful, The Bestower of Mercy.

Allah, The Most High, said:

يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا قِيلَ لَكُمْ تَفَسَّحُوا فِي الْمَجَالِسِ فَافْسَحُوا يَفْسَحِ اللَّهُ لَكُمْ ۖ وَإِذَا قِيلَ انْشُزُوا فَانْشُزُوا يَرْفَعِ اللَّهُ الَّذِينَ آمَنُوا مِنْكُمْ وَالَّذِينَ أُوتُوا الْعِلْمَ دَرَجَاتٍ ۚ وَاللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ

O you who believe, when you are told to make space in the gatherings (for others), then make space, Allāh will make space for you (in your homes and provision in Paradise). And when you are told to arise (towards goodness, the prayer, or battle), then depart. Allāh will raise those who believe among you (for their obedience to the Messenger) and those given knowledge by degrees (over others). And Allāh is all-aware of whatever you do. [Al-Hujurat 11] [a]

This is a practical code of behaviour commanded by Allah to His believing slaves- that when they come together in one of their gatherings, some of them or some of those who have already arrived should make room (for others), for indeed it is part of good etiquettes to make room for him (i.e. the other person) to reach his goal. And this is not to harm the one who is (already) in the gathering in any way; rather he enables his brother to reach his goal without him being harmed, and reward is given in accordance with a deed. Indeed, whoever makes room, Allah makes room for him, and whoever shows generosity to his brother, Allah will show him generosity.

وَإِذَا قِيلَ انْشُزُوا

And when you are told to rise up.

Meaning: To rise up and retire from your gathering for an (obligatory or important) need [i.e. prayer etc], then [فَانْشُزُوا – rise up] – Meaning: proceed towards the fulfilment of that beneficial affair, for indeed the fulfilment of the likes of these matters is connected to knowledge and Iman.

And Allah, The Most High, will exalt in degree the people of knowledge and Iman in accordance with what He has portioned out for them from knowledge and Iman.

وَاللَّهُ بِمَا تَعْمَلُونَ خَبِير

And Allah is all-Aware of whatever you do.

Meaning: Allah, The Most High, rewards every performer of deeds in accordance with his [or her] deeds-if they are good, there will be good recompense, and if evil, there will be an evil recompense.

In this verse is a virtue of knowledge, whose beautification and fruitful outcome is to discipline oneself with its etiquettes and act in accordance with what it necessitates.
