Islamic Interpretation of Dreams (Ibn-i Sirin):
(Jailer) In a dream, a blacksmith represents a strong personality, a leader, or a powerful and a skillful ruler.
A blacksmith in a dream also represents the angel of death.
Seeing a blacksmith in a dream or being one, indicates both happiness and adversities.
To be brought before a blacksmith in a dream means an accident that will bring one before a person in authority for intercession. Otherwise, it could mean seeking the fellowship of a worthless person.
If one sees a sick or a deceased person sitting with a blacksmith in a dream, it means that he is in hell, and particularly when his face is blackened from the smoke, or it could mean that he may be imprisoned.
