When hearing about another person’s dream, neither immediate dismissal nor treating it as a binding legal proof is sound. Dreams may differ in clarity, and the dreamer’s memory and narration are not identical to the experience itself.
Example 1: A dream encourages someone to improve an already established aspect of good character; this is understandable.
Example 2: Someone claims a new religious obligation now applies to everybody because of a dream; this conclusion does not follow from the report.
فِي الْمَنَامِ is a prepositional phrase specifying the state or setting: “in a dream.”
