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 upbring righteous people and have an increase in population at the same time, it is preferred to prevent polulation growth and give priority to the upbringing of righteous children.
2- The Role 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 outside 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 Role 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 have in this regard is warning against the destructive role of consuming unlawful food. The foetus that originates from the consumption of unlawful food will lead to 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 foetus, throughout the period of pregnancy and after giving birth.
4- The role of the Method of Copulation 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 transgression of unlawful birth.
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.
