This study aimed to identify and study the different and varied consumer’s behavior models well in order to provide a proposed model of consumer behavior for the Muslim within the existing models which are used by marketers for the sake of studying and analyzing the factors affecting consumer behavior and as a result affect his decision to purchase. In order to conduct this study, the inductive, deductive and the descriptive approach were used to devise a model of Muslim consumer behavior within the existing models in this field. This study has come up with several results, the most important of which are: 1- All models developed to explain the behavior of the consumer partially fit in the interpretation of the behavior of Muslim consumer because it ignored the role of faith comes first in influencing the behavior of the Muslim consumer. 2- The behavior of the Muslim consumer in the first place is influenced by religious values and moral standards. 3- Marketers should focus on the necessary and semi-essential products, then the luxury ones because the Muslim consumer is controlled by his faith in this area which urges him to mediate and not wasteful. 4- We, as Muslim, urgently need to frame all our marketing activities, especially the promotion, to be in full compliance of what is stated in our Islamic belief in many Quran and Hadith texts. 5- The Muslim consumer is in dire need of products that correspond to his actual needs, and advertisement commensurate with his doctrine and they should also designed to include messages that do not carry what contradicts with religion and morality.
