Objective: Childbearing is considered one of the fundamental pillars of the family within the Islamic–Iranian value system and holds a significant place in religious texts. Qur’anic and narrative teachings emphasize the importance of having children and their role in strengthening the foundations of the family. One of the key factors in promoting the culture of childbearing and consolidating family stability is the observance of lawful and pure livelihood. This study aims to examine the role of lawful sustenance (halal rizq) in strengthening the family with a focus on childbearing, based on Qur’anic verses, narrations, and the statements of religious scholars.
Materials and Methods: This research was conducted using a library-based approach with a descriptive–analytical method. The sources include verses from the Holy Qur’an, narrations of the Infallibles (AS), the works of commentators, and related studies in the fields of family, Islamic economics, and population. After data collection, qualitative content analysis was applied to review and interpret the findings.
Findings: The analysis of religious texts reveals that childbearing is not only an ethical recommendation but also a necessity for the vitality and continuity of the Islamic family. Among the crucial factors in fostering a tendency toward childbearing are the belief in Divine providence and commitment to earning lawful sustenance. Lawful livelihood enhances faith, God-consciousness, self-awareness, and belief in the Hereafter, thereby creating psychological peace and economic security within the family, which in turn increases the willingness to have children.
Conclusion: The findings indicate that lawful sustenance, by strengthening religious and moral foundations, plays an effective role in consolidating the family and promoting a culture of childbearing. Clarifying this relationship can serve as a strategic guideline for cultural and social policymaking aimed at enhancing population growth and family stability in the Islamic–Iranian society.
