Family is societal institution that is conceptualized as “Vital” and “Valid” its importance is emphasized by
social conservatives across cultures. Consanguinity is usually socially motivated and can be genetically harmful; it is a
state of being descended from a common ancestor. It has been practiced by many societies around the globe from time
immemorial, and a part of most civilizations as far back as the Old Testament of the Bible, and in the Arab world before
the emerging of the Islam, and therefore, it is not monopoly where Islamic faith prevails.
We scrutinize the effect of consanguinity on family health, its benefits and its detriments, and how should be tackled on
medical and policy levels. We also pursue the Islamic attitude and discourses on the marriage custom, law, ethics and
principles. Attention is then drawn to the cultural influences and challenges in the Arab word.
