Ruling on an
    employee and agent of the company owner taking a commission on sales
Question

                I work as an employee in a company and
      the owner of the company asked me to sell some land he owns that has nothing to do with
      the work of the company. I showed it to a number of landlords and real estate agents until
      I got a good offer and the sale was completed. The purchaser offered me a sum of money. Is
      it permissible for me to take it in return for acting as a middleman?
Praise be to Allah.We put this question to Shaykh Ibn ‘Uthaymeen, who
    replied:
What was offered to him?
We said: he was told, “You have put a lot of effort into this, so
    you deserve a reward.”
The Shaykh asked: Was this before the sale or afterwards?
We said: After the sale.
The Shaykh said: there is nothing wrong with it and there is no sin on
    him.
We said: And if it was before the sale?
The Shaykh said: That would not be permissible because then he may try
    to do the purchaser a favour.
