The Holy Prophet based business dealings strictly on truth and justice. He has strongly disapproved all transactions which involve any kind of injustice or hardship to the buyer or the seller. He wanted that both, the buyer and the seller, should be truly sympathetic and considerate towards each other. One should not take undue advantage of the simplicity or ignorance of the other. The seller should not think that he has unrestricted liberty to extort as much as possible from the buyer. He has to be just; he should take his own due and give the buyer what is his.
