Murabaḥah is a term for a sales contract where the buyer and seller agree on the markup (profit) or "cost-plus" price for the item(s) being sold, which covers the cost of what?
Markup (business) Markup is the ratio between the cost of a good or service and its selling price. It is expressed as a percentage over the cost. A markup is added onto the total cost incurred by the producer of a good or service in order to cover the costs of doing business and create a profit. The total cost reflects the total amount of both fixed and variable expenses to produce and distribute a product. Markup can be expressed as a fixed amount or as a percentage of the total cost or selling price. Retail markup is commonly calculated as the difference between wholesale price and retail price, as a percentage of wholesale. Other methods are also used.
Nikah 'urfi Nikah 'urfi is a "customary" Sunni Muslim marriage contract that requires a walī (guardian) and witnesses but not to be officially registered with state authorities. Couples repeat the words, "We got married" and pledge commitment, although there are many other informal ways in which people marry `urfi. Usually a paper, stating that the two are married, is written and at least two witnesses sign it, although others may record their commitment on a cassette tape and use other forms of documentation. Most Arab countries do not recognize 'Urfi marriages and do not allow partners to get a 'legal' divorce since the government does not recognize the legality of the marriage in the first place. Sometimes these relationships are a way for people to have sex with each other within what is perceived to be a licit framework. Nevertheless, the relationship is often kept secret from family members.
