As the primary social institution, the family is formed through marriage and evolves through the birth of children, holding a special status in Islamic teachings. Unfortunately, past population control policies and Western-oriented ideologies centered on economic challenges have diminished the inclination toward childbearing, leading to the spread of the single-child culture and an aging youth population. This research, employing a descriptive-analytical method and utilizing library resources, examines the concept and importance of childbearing as the fundamental purpose of marriage. The findings demonstrate that the Holy Qur'an regards children as a divine blessing and a support for parents, encouraging Muslims to expand their lineage by emphasizing the significance of marriage. This study explores relevant verses and narrations to highlight the benefits of child-rearing and presents Quranic solutions to encourage families. Beyond the spiritual dimension, the Holy Qur'an introduces childbearing as an effective factor in strengthening the economy and national production. Consequently, by revisiting the sublime perspectives of Islam, this article aims to present encouraging strategies and counter erroneous economic misconceptions, explaining the necessity of population growth as a strategy for individual and social excellence to provide a foundation for shifting societal attitudes.
