Praise be to Allah, and peace and blessings be upon the Messenger of Allah. To proceed:
Yes. It is established that the souls of believers meet and visit one another in Barzakh, and that they ask about the condition of the living and those who preceded them in death.
It is authentically reported from the Prophet ﷺ that when the soul of a believer is taken and the angels ascend with it, the souls of the believers receive it and rejoice at its arrival. They ask it about some of the living, saying: “What happened to so-and-so?” If that person is still alive, the soul informs them about him. But if he has died and his soul has not yet reached them, they say: “He has been taken to the abyss.” The hadith was narrated by al-Nasa’i and authenticated by al-Albani.
Shaykh al-Islam Ibn Taymiyyah, may Allah have mercy on him, stated that souls meet and visit one another in Barzakh. Their ranks may differ: the souls of those who are closest to Allah are in a higher position than others. Nevertheless, they may gather and visit one another by Allah’s permission, just as they used to gather in this world.
The meeting of souls does not require their graves to be close to one another. The graves of their owners may be far apart in this world while their souls meet. Likewise, a believer may be buried next to a disbeliever without their souls meeting, because souls differ according to the deeds of their owners. The Prophet ﷺ said:
“Souls are like recruited soldiers: those among them that recognize one another are compatible, and those that do not recognize one another differ.” Narrated by Muslim.
Ibn al-Qayyim, may Allah have mercy on him, said that souls in Barzakh are of two types: souls being punished and souls enjoying blessings. The blessed souls meet, visit one another, and remember what happened in this world. Each soul remains with souls that resemble it in their deeds. As for the souls being punished, they are occupied with the punishment they are experiencing.
This is supported by what Allah Almighty has informed us about the martyrs:
“And they rejoice for those who have not yet joined them, who are left behind.”
This indicates their happiness for their brothers who will join them.
As for the hadiths that explicitly mention the dead visiting one another because of improving or beautifying the shroud, none of them has been authentically established. Therefore, they should not be used as evidence.
Accordingly, the basic principle that the souls of believers meet and visit one another during the life of Barzakh is established. As for the details of how this occurs and the true nature of the life of souls in Barzakh, these are matters of the unseen. We know of them only what has been established by authentic evidence.
And Allah knows best.
