Are glad tidings different from prophecy in terms of the possibility of their occurrence, and what is the relation of this to the Prophet's narration of 16 prophecies, among which is the abundance of visions, and does a natural question lead to disbelief?

There is no prophethood after the Prophet, peace and blessings be upon him, except for the glad tidings, which are righteous visions. True prophethood is exclusive to the prophets and occurs only to them. As for visions, they occur to individual believers and continue after the death of the Prophet, peace and blessings be upon him.

Innate questions that stem from a person's natural disposition do not render their asker an unbeliever, because Allah fashioned humanity upon monotheism. However, questions that involve mockery of religion or objection to Allah's wisdom are not innate and contradict faith.
