I work in an IT company, and sometimes I get involved into admission consultant, wherein my friend is actual admission consultant and if anyone comes to me to get admission in any college. I refer them to my friend. I get the quotation from my friend and tell the candidate the fees I have given including my fees.
For example: If my friend tells me X amount then I go and tell the candidate X+Y amount, where Y is my fees and the candidate is not aware of the Y amount.
Is this kind of earning halal in Islam?
