This happens to the soul after death.

Imam al-Qurtubī mentions in his exhaustive work regarding what happens after death, al-Tadhkira fī Ahwāl al-Mawtā wa Umūr al-Ākhira, that the souls of Believers will meet one other in the skies. This is similar to what Ibn al-Qayyim al-Jawziyya mentions in Kitab al-Rūh about the souls of the deceased meeting one another, visiting one another, and making remembrance of the Almighty (dhikr) with one another. He mentions that this is specific to the souls of the believers because they are in a state of blessing, free to roam, as opposed to the souls of the disbelievers, who are tormented and restricted. Imam Ibn al-Qayyim continues,

“Each soul will be with its companions who are at the same [level of] good deeds, and the soul of our Prophet Muhammad (may Allah bless him and grant him peace) is with the Highest Companion [Allah, Most High]. Allah says, ‘Whoever obeys Allah and the Messenger, they are amongst those whom Allah has blessed, of the Prophets, those of great faith, the martyrs, and the righteous. What excellent companions are they!’ [Quran 4:69] The togetherness [mentioned in this verse] holds for this abode, the Intermediary Realm (barzakh), and the Abode of Recompense [i.e. the afterlife]. A person is with whom he loves in all three of these abodes.”
