What is the expiation for someone who narrated a dream, not knowing that it was forbidden?

Lying in a dream is forbidden, and its expiation is by repenting to Allah Almighty. This is done by feeling remorse, abandoning the sin, and resolving not to return to it in the future. Whoever repents before the sun rises from its west, Allah will accept their repentance. If you regret your lie in the dream and resolve not to return to it, then Allah will forgive you.
