Background/Objective: There are concerted efforts to halt down population growth and reduce maternal and child mortality rate in Nigeria through family planning. Studies show that these efforts have not been yielding the desired results. Nigeria is the most populous country in Africa and the seventh globally. The National Population Commission estimates the country's population at 198 million. The aim of this work is to promote Inter-faith dialogue on Family Planning (FP). Methodology: Nigerian Supreme Council for Islamic Affairs (NSCIA) works with the Nigerian Urban Reproductive Health Initiative (NURHI) with a view to increase contraceptives uptake among women, adolescents and people within the child bearing age through advocacy, demand creation and service delivery, plus monitoring and evaluation, starting with a research to understand the local context, identify religious leaders and project implementers. Through these, views, ideas and attitudes that influence family planning in close collaboration with Inter-faith forums have been explored. Results: The evaluation carried out, found 30% higher contraceptive uptake among women exposed to family planning messages from religious leaders compared with those without such exposure. Men who listen to sermons in Juma'at and Church services support their women to access family planning services. Conclusion: Faith and family planning interact in complex ways at personal, community, and government levels. Therefore, it is pertinent that the leaders of the two major faith in the Country, Islam and Christianity both work together towards providing appropriate messages on family planning in all Inter-Faith Collaborations.
