Islam is pro-business. The Sharia contains detailed rules as to how business should be conducted, which attempt to ensure support for the weak. Any business activity that is fair and beneficial to both parties and is transacted by mutual consent is lawful, but an activity involving uncertainty or an unfair assumption of risk is not allowed. For example, renting agricultural land for money is forbidden because the renter has a guaranteed return while the cultivator takes the whole risk that the crop will fail.
A Muslim may not deal in things, such as intoxicants, swine, or idols, the use, which is harmed. The Sheria prohibits dealings in stolen or usurped property. There is no statue of limitation in Islamic law and the passage of time cannot deprive an original owner of his right in property. The principle of caveat emptor is not recognized and the Sheria require a Muslim to make every thing clear about an article he shells including any defects.
The Sheria prohibits the charging of riba (usually translated as interest) no money lent.
A few Islamic scholars make a distinction between interest and usury and say that interest can at times be legitimate. Though commercial banks in Kuwait lend money at interest, the religious prohibition on riba has led to the development of Islamic banking.
Western forms of insurance, such as insurance carry the risk that one party will receive all the benefits with nothing for the other party. In addition, Muslims deal with conventional insurance companies as they invariably lend their preium monies on interest.
