Stealing from the Sacrifice
Scholars have said that if a person dreams of stealing something from a sacrifice, it may indicate lying about God. Some interpreters mentioned that if a sick person dreams of sacrificing, their vision might signify their death or suffering. As for seeing Eid al-Adha, it indicates the return of past joy and salvation from destruction, in remembrance of Ishmael's salvation from being sacrificed.
