What is the meaning of "A vision is one part of forty-six parts of prophethood"?

The meaning of "a vision is one part of forty-six parts of prophethood" is that the duration of revelation in a dream, which is six months, when compared to the duration of prophethood, which is twenty-three years (276 months), constitutes one part out of forty-six parts. The number of parts mentioned in the hadiths varies, and all narrations indicate the emphasis on the importance of visions.

People are categorized in relation to visions as follows: Prophets (all their visions are true), the righteous (most of their visions are true), others who are of unknown piety (their visions can be true or be jumbled dreams), and the wicked (most of their visions are jumbled dreams), and disbelievers (truthful visions are rare for them). The vision of a righteous, truthful believer is what is considered a part of prophethood, for truthfulness in speech leads to truthfulness in visions. As for the disbeliever and the wicked, their visions are not considered parts of prophethood, even if they occasionally come true.
