Is this enough for forgiveness?

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
Please clarify from your uncle what he meant by forgiving you. Is he absolving you from returning the money to him? If he has not absolved you, the money must be returned to him. In either case, turn to Allah in repentance for the crime of usurping.[1]
