(4) Murabahah (Mark-up sale): This is form of trading arrangement where a party buys an asset and sells to another party for a price which consists of the cost plus a margin of profit. Murabahah can be of two kinds - cash murabahah and credit murabahah. Cash Murabahah is buying an asset and selling it for a marked up price for cash. Credit Murabahah is a type of trading arrangement where an asset is bought by one party and sold to another party for a deferred price. The price includes cost plus a margin.

This type was traditionally used in agriculture where certain quantity of agricultural products would be sold in the beginning of a season for advance cash payment and goods to be delivered after a specified time. For example; 'Ali pays to Qadir Mrf2000 for 400 kg of watermelon today and the delivery of 400 kg of watermelon is agreed to be 6 months from today.
(6) Bay'u al-Istisna (Contract Manufacturing): This is also a special kind of sale which is applied in the manufacturing sector. In the case of Istisna, a buyer places an order for a particular product with well defined specifications, then the seller (producer) accepts the order and produces the product for specification. The price will be settled once the product is delivered to the buyer. Special arrangement for price settlement could be arranged such that installment payments are made as production completes stage by stage.

AITAB (Al-Ijarah Thumma Al-Bay'u) is an example. Under this contract, an Islamic bank buys, say a car, from a manufacturer and rents it to a customer for a defined period of time. At the end of the lease period, say 15 years, the bank customer will buy the asset from the bank for a nominal price or the bank can give the car as a gift or hibah. The lease period and the rental will be determined such that at the end of the lease period the bank makes revenue over the break-even.
(9) Bay'u al-'Inah (back-to-back sale): Although shar'iah scholars have disputed on the permissibility of bay'u al-'inah, this contract is used in some countries. Bay'u al-'inah is popular in Malayisa, but the popularity is declining gradually. Bay'u al-'inah is considered shari'ah non-compliant in GCC countries, because majority of scholars such as hanafi, hanbali and maliki say bay'u al-'inah is illegal. Under bay'u al-'inah, a seller sells an asset to a buyer for deferred price and immediately buys it back from the buyer for cash, which much lower price than the deferred price. There are three types of bay'u al-'inah;
(a) The seller sells to the buyer at a higher price to be paid later. After delivery to the buyer, the seller buys in cash at a much lower price.
(b) The seller sells a product for deferred delivery for, say RM800. After delivery to the buyer, he sells it to a third party for a lower price, say RM400. The third party then sells it to the first party for, say RM400. This is called al-tawarruq.
(c) A man who wants to borrow, say RM800. The creditor refuses to lend using qard contract. He sells an asset to the borrower for deferred price of RM1000, the market price will be RM800. The lender makes RM200 profit from this transaction. He will be paid RM1000 for a good that cost RM800 by the borrower later.
