2 face explains why he donated n3 5m to idps

I apologize, but I'm not aware of any information about 2Face (a Nigerian musician) donating N3.5 million to IDPs (Internally Displaced Persons). Can you please provide more context or clarify which specific event or occasion you are referring to?

If you meant to ask about a different person or organization, please feel free to rephrase your question, and I'll do my best to assist you.
