have in this regard is warning against the destructive role of consuming unlawful food. The fetus that originates from the consumption of unlawful food will end up with the deviation and aberration of the child. The families who desire happiness for their children must avoid eating prohibited food. Such precautions regarding food must be specifically observed by mothers during their pregnancy, and mothers should not even participate in any feast whose food is doubtful.
Moreover, the consumption of certain kinds of food and fruits is recommended for fathers and mothers prior to the formation of the fetus, throughout the period of pregnancy and after giving birth.

4- Legitimate Copulations

According to Islam, lawful and unlawful sexual relations have a fundamental role in the positive and negative characteristics of a child. From the viewpoint of the Prophet of Islam (s.a.w.), the first Divine bounty given to a person is the legitimacy and purity of birth. Many of the social vices are the results of the offences committed by illegitimate children. This does not mean that illegitimately born children can never choose the correct path of life, even though without doubt choosing the correct path is difficult for them.
The fourth chapter of this section mentions the positive effects of legitimacy of birth in the formation of the personality of the child and the warnings against illegitimate births. In addition to this, for the felicity of the future of the children, it is recommended that parents be mindful of this at the time of sexual intercourse. At the end of the chapter, some traditions will be mentioned about the role of the circumstances and particular times of sexual intercourse and their effects in the future of the child.¹

Population Control from the Viewpoint of Islam:
Pondering on the above-mentioned, it becomes clear that the purpose of the traditions that encourage Muslims to have more children is to arrange a program for producing as many healthy and righteous children as possible in order to create an exemplary society. In this case, not only does Islam oppose the control of the growth of population, but it supports the increase of the population of a Godly society. However, in the conditions brought about by economic difficulties and cultural corruption where families do not have the ability to raise qualified children, the increase of children is not desirable and there is a need for family planning to control the population.
Therefore, according to the instructions of the leaders of Islam, the Islamic government and the Muslim families are obliged to organise their programs aimed to increase the population based on their economic and cultural abilities. If it is not possible to raise righteous people and have an increase in population at the same time, it is preferred to prevent population growth and give priority to the upbringing of righteous children.

2- The Function of Heredity

The second chapter explains the positive and negative roles of heredity in the development of the personality of the child as mentioned by the leaders of Islam. Accordingly, not only does the child inherit the physical features of its parents, but it also inherits their psychological and innate characteristics (such as bravery, generosity, and good temper).
A noteworthy point is that according to Islamic traditions, the mothers play a greater role than the fathers in this regard. Therefore, those who seek to raise healthy, strong, handsome and righteous children must be more mindful in choosing their wives.

3- The Function of the Parents’ Food:

Chapter three explains the role the parents’ food intake has in the future of the child. The most important advice the leaders of Islam
