Islamic Interpretation
In a dream, rust or corrosion symbolizes moral decay and hypocrisy, representing an ostentatious and affected person who outwardly displays piety, devotion, and righteousness in public, yet harbors contempt, corruption, or wrongdoing in secrecy and darkness. It may also signify a thief, highway robber, or someone weak, sluggish, negligent, and lacking resolve, as well as a miserly individual who hoards wealth, withdraws from people, and prefers isolation, reflecting inner deterioration that slowly eats away at character and integrity just as rust consumes metal.
