Ako dosť podobne ale tvaria sa že no interest :P
ale hlavny rozdiel vidim v nekonplikovanosti ich trenzakcií..arms length...a v tom že neuznavaju derivaty..

The basic principle of Islamic banking follows the laws of Sharia, known as Fiqh al-Muamalat (Islamic rules on transaction). The term “Islamic banking” is synonymous with “full-reserve banking” and “Sharia-compliant banking.” The most prominent feature of these laws is usury – the prohibition of paying or collecting interest on funds. The Islamic terminology for this is riba or ribaa. The Sharia also forbids engagement in investments that include financial unknowns such as buying and selling futures, as well as businesses that are haraam – dealing in products that are contrary to Islamic law and values such as alcohol, pork, gossip or pornography. These principles apply to all individuals, companies and governments.
