Q: I organised a contract for another person. Am I allowed to charge him a fee for this?
A: No, this is bribery. Nowadays most contracts and tenders are secured through bribes. Bribery is haraam. Rasoolullah (sallallahu alayhi wasallam) cursed the giver and the taker of bribes. If a contract or tender cannot be secured through halaal means, rather avoid it. There will be no barakat in earnings that stem from bribery.
