Hadith.1655 - A man came to Amir al-Mu'minin (Imam Ali ibn Abi Talib (as)) and said: "O Amir al-Mu'minin, I have acquired wealth through questionable means. Is there repentance for me?" The Imam (as) replied: "Bring me its Khums." The man brought him the Khums, and the Imam (as) said: "It is yours. When a person repents, his wealth repents with him."
