Are Paradise and Hell, in terms of the destiny of entering them, an absolute unseen, or a relative unseen that can be glimpsed through visions and inspiration?

Entry into Paradise is part of the absolute unseen (al-Ghayb al-Mutlaq), and it cannot be definitively asserted for a specific person except through an authentic text from revelation. It is not disclosed through visions or inspirations. This is indicated by the hadith of Uthman ibn Madh'un, may Allah be pleased with him, where Umm Al-Ala said to the Messenger of Allah, peace and blessings be upon him: "May Allah have mercy on you, Abu As-Sa'ib. I bear witness that Allah has honored you." The Messenger of Allah, peace and blessings be upon him, said: "How do you know that Allah has honored him?" I said: "I do not know, may my father and mother be ransomed for you!" Then the Messenger of Allah, peace and blessings be upon him, said: "As for him, certainty (death) has come to him from his Lord, and I indeed hope for good for him. By Allah, I do not know, and I am the Messenger of Allah, what will be done with me!"

This indicates that Paradise cannot be definitively affirmed for a specific individual unless the Law-Giver (Allah/His Messenger) has explicitly stated it for them, such as the Ten Promised Paradise and others. "We do not assert Paradise for anyone except what the Law-Giver has explicitly stated," as it is mentioned in Al-Aqidah Al-Tahawiyyah: "We hope that Allah will forgive the virtuous among the believers and admit them into Paradise by His mercy, but we do not feel secure concerning them, nor do we testify for them with Paradise. We seek forgiveness for their wrongdoers, and we fear for them, but we do not cause them to despair."
