4.1. Description & Elaboration  

Gharar in the financial transaction may render the financial contract totally null and void, or it may lead in some cases to compensation. The term gharar literally means gharara which means danger or fraud, the source term al-taghrir refers to exposure to danger. The linguistic original of the term gharar refers to items with a likeable appearance and disliked reality. (Wahbah Al-Zuhayli, Financial transactions in Islamic jurisprudence, vol. 1, p. 82. Ali Al Khafif, Ahkam Al Muamalat Al Shariayyah, p. 6). Or it refers to something which cannot be defined or specified. (Ala'Eddin Kharofa, Transactions in Islamic law, p. 80.). The word of gharar has been used to mean risk, uncertainty and hazard. (Mohammad Hasim Kamali, Islamic commercial law, p. 84.). In the technical meaning, the Muslim jurists provide various definitions which are related to the uncertainty and ignorance of one or both parties of the substance or attributes of the subject of sale, or doubt of subject matter existence at the time of contract.

 
The maliki define gharar as: "what is not known to exist in the future, e.g. birds in the air and fish in the water". (Al qarafi, al furuq, vol. 3, p. 265). Shafi'is defines it as: "gharar is that which admits two possibilities, with the worse consequence being the more likely". (Al Isnawi, Al sawl sharh minhaj al usul, vol. 2. p. 89).  Shairazi said: "gahrar is that whose nature and consequences are hidden". (Al Shairazi, Al Muhadab, vol. 1, p. 262.). In this context the sale of gharar is any sale that incorporates risk that affects one or more of the parties to the contract and may result in loss of his property. (Wahbah Al-Zuhayli, Financial transactions in Islamic jurisprudence, vol. 1, p. 83.). The gharar is risk in the sense of lack of certainty regarding the existence of an object. The gharar sale is consequently: the sale of that which is not known to exist or not, whose measure is not known to be large or small, or that is undeliverable. (Wahbah Al-Zuhayli, Financial transactions in Islamic jurisprudence, vol. 1, p. 84). The Muslim jurist agreed that the gharar sales is not valid, and easily may render the transaction totally null and void, however it is important to record that gharar in Islamic law is classified into three categories:
 
A: The substantial gharar (ghara kathir): This type of gharar is unanimously prohibited and not accepted in Shariah such as selling a bird in the sky. This is considering an excessive gharar which renders the financial transaction invalid.
 
B: The minor gharar (gharar yasir): This type of gharar is unanimously allowed by Shariah such as buying a foundation of house; the jurists are in agreement that this minor gharar is tolerable and permitted. (See: Ali Al Khafif, Ahkam Al Muamalat Al Shariayyah, p. 356).
 
C: The moderate gharar: This is moderated gharar, this category falls between the two previous categories, however there are few legal opinions from the Muslim jurists with regards to this category, whether this gharar belongs to the first category or to the second one.
 
The Maliki and Hanbali School of law and other Muslim jurists are  of the opinion that the minor gharar in sale is permitted and accepted in Shariah, and it does not affect the business transaction, this legal Shariah approach will facilitate the business transaction and smoothen the trade.
 
According to Imam al Nawawi, there are two major items to which minor gharar are applicable: 
· Items which are included as part of a sale and that may not be sold separately (e.g. foundation of a house).
· Items that are customarily tolerated, either due to its insignificance, or the difficulty of identifying, e.g. the fees for using a bathroom where the amount of water used in the bath may vary. (Al Nawawi, Al Majmou, Vol. 9, p. 280).
