(Islamic finance)

Suppose that on June 5, 2015 Mr. Ali invested $3000 in United Industries (UI), which was declared to be involved in Shariah Compliant Business and distributes the profit to its shareholders on monthly basis. On July 15, 2015 UI acquired a beverage company, which was primarily involved in making alcohol. On September 15, 2015 Mr. Ali came to know about the UIs non-Shariah Compliant acquisition and dont know what to do as he is suspecting that part of the earning he received from UIs profit is not halal. Being an Islamic Finance graduate, what would you suggest him to clean his earnings? Your answer shouldnt exceed 50 words.
