Munājāt: private talk with God
Sufis use this word for the quiet conversation between a person and God. Someone coming out of long closeness carries it back into ordinary company without meaning to. The closeness itself does the work, the way years with a close friend end up shaping how you talk. The change settles in while a person's attention is turned fully toward the one they are speaking with.
Tajallī: God showing Himself
Ibn Arabi and al-Ghazali both use this for God making Himself known in something. Whatever brightness appears in a person after such nearness arrived from outside them. The moon has no light of its own, and everything it gives back it first received. A person is the place the light lands, and treating it as personal property gets the whole thing backwards.
I become the hearing with which he hears: nearness changes the one who draws near
In a saying of the Prophet, God describes drawing so close to a servant that He becomes their hearing and their sight. Closeness like that works its way into ordinary parts of a person: their voice, their looking, their patience with people. Someone kept near for a long time comes back changed in ways they never worked at, and everyone else sees it before they do.
Fanāʾ: the self dropping out of view
Junayd and Bistami use this for the moment a person stops keeping an eye on themselves. Attention can only sit in one place, and while it rests on God the self goes unwatched. Nobody in that condition is checking how they seem or grading how they are doing. A person who cannot report on their own state was fully occupied with something else.
ʿUjb: being pleased with yourself
Al-Ghazali treats this as the quiet satisfaction a person takes in their own goodness, and he counts it among the worst inner faults. It turns a gift into a credential. Someone who catches themselves being admirable starts managing it, checking who saw, arranging for more. A person who never catches sight of it has nothing to start protecting.
