The broker’s wage
Question
Question: ‘Umar built a house, and for this he needed iron. He went to buy iron, taking an experienced person with him, and there he bought iron worth 5000 rupees. Afterwards he learned that the shopkeeper had given that experienced person 50 rupees because he had brought a customer to his shop — or whatever had been agreed between them. Is taking this commission permissible or not?
