Working as an intermediary between businessmen and his company in return for payment
Question

                I work in a petroleum company as a normal clerk. Some businessmen have offered me to work as a mediator between them and the company I work for. Knowing that I do not work in the section of purchasing, and I do not have any effect on making decisions in this company. Some purchasing commissioners stipulate rishwa (bribe) on the businessmen, and unfortunately this commissioner is the one who receives the offers and he has an effect sometimes on making the decision.  

What is the Islamic ruling on this trading transaction?.
Praise be to Allah.
    If you do not work in the purchasing department and you have 
    no influence on decisions about dealings and purchases, then there is 
    nothing wrong with you working as an intermediary between the businessmen 
    and the company, because the basic principle is that it is permissible for a 
    person to work as a broker in return for a set fee or for a percentage of 
    the goods bought and sold, according to the agreement. 

    But that is conditional upon the goods and projects being 
    things that are not forbidden according to sharee’ah. 

    But if a person’s work involves negotiating or dealing with 
    these people, if he has some influence of the decisions that are made, then 
    he has no right to take anything in return for his work, because he will be 
    focusing on his own interests and not looking at the interests of the 
    company for which he works, al-Bukhaari (7174) and Muslim (1832) narrated 
    that Abu Humayd al-Saa’idi (may Allaah have mercy on him) said: The Prophet 
     (peace and blessings of Allaah be upon him) appointed a man from Bani 
    Asad who was called Ibn al-Lutbiyyah to collect zakaah. When he came he 
    said: This is for you, and this was given to me (as a gift). The Messenger 
    of Allaah  (peace and blessings of Allaah be upon him) stood up on the 
    minbar and praised and glorified Allaah, and said: “What is the matter with 
    an agent whom I send, and he comes back and says, ‘This is for you and this 
    was given to me’? Why doesn’t he sit in the house of his father or the house 
    of his mother and see if he is given anything or not? By the One in Whose 
    hand is the soul of Muhammad, no one of you gets anything from it 
    (unlawfully), but he will bring it on the Day of Resurrection, carrying it 
    on his neck, whether it is a groaning camel, a lowing cow or a bleating 
    sheep.” Then he raised his arms until we saw the whiteness of his armpits, 
    then he said: “O Allaah, have I conveyed (the message)?” three times. 

    It says in Fataawa al-Lajnah al-Daa’imah (13/131): It 
    is permissible for the broker to take a set percentage of the price for 
    which the goods are sold in return for finding buyers, and he may take it 
    from the seller or the buyer according to the agreement, without any 
    unfairness or harm. End quote.
