Le comportement du musulman en matière de crédit à intérêt face à la contrainte religieuse[The behavior of the Muslim regarding credit with interest in front of the religious constraint]

Contrary to the Islamic laws considered as social standard governing the behavior of the Muslims, the facts relative to most of the Muslim countries show that the detention of a conventional bank account considered as illicit because it is generative of the rate of interest and savings is more spread where the population is important. In this article, we divert the conditions under which these principles are not respected. We demonstrate that the cost to inquire some on the others can constitute a brake with care of the Islamic laws. Indeed, the more the population is important, the more the information is scattered and more its cost is raised reducing the effect of social cost of the standard with regard to the earnings expected from the detention of the account.
