Religious perspectives on family planning are not well understood or explored; however, this document sheds light specifically on Islamic thought regarding the diverse methods of family planning. Initiated by Senegalese religious leaders seeking a contemporary and comprehensive resource, the text is co-authored by Imam El Hadj Moustapha Guèye and Imam Mouhamadou Takhiyou Kane, two of Senegal’s foremost scholars on Islam and family planning. The Islamic Argumentation on Birth Spacing presents the Islamic justifications for birth spacing through a careful examination of the teachings of the Qur’an, the hadiths, and leading scholars on Islam. This work represents a new approach in family planning promotion in Senegal by incorporating teachings not only from Muslim scholars outside of Senegal, but also from respected Senegalese religious leaders and scholars. The work examines the permissibility of different family planning practices within Islam, but goes a step further by addressing the main religious arguments against family planning. Although many of the opinions and teachings presented come from Senegalese leaders and scholars, the content is applicable both in Senegal and beyond. This resource, available in French and Arabic, was created as part of a project supported by the William and Flora Hewlett Foundation.
