Praise be to Allah.
We put this question to Shaykh Muhammad ibn Saalih al-‘Uthyameen, may Allaah preserve him, who answered:
No, he does not have to do anything.
Is that because he has repented?
So we can say that because he has repented, he does not have to dispose of the money a second time?
Yes, he does not have to do anything.
And Allaah knows best.
