Ma`rifat Farhangi Ejtemaei

There are various theories about population size; including population increase theory, population decrease theory, population stability theory and optimal population theory; however, the population view of Islam has been considered to be continuously increasing among the scientists of "demography". On the other hand, there are various interpretations regarding Islam's opinion on this issue, including maximum fertility and optimal population; but having children as much as possible can be considered a new interpretation for it. The purpose of this research is to analyze the existing interpretations from the demographic point of view of Islam and to prove the selected interpretation. The study method of this research is documentary and its method is ijtihad-interpretive. Using documentary and ijtihad-interpretive method, this research has been conducted. The most important finding of this research shows that according to the selected explanation, it is desirable for every family to adopt children in accordance with their health status and taking into account their other tasks, to the extent that they can, in order to provide their share of the population required by the Islamic society. Avoiding the problems of "maximum fertility" and "ideal population" interpretations, this interpretation is supported by solid evidence and has features and advantages.
