Genetic Understanding of Effects of Consanguinity (Inbreeding) and Breast-Feeding-Based Consanguinity in Islam (Medical and Social Aspects)

Bilal Ghareeb



Genetics concepts have repeatedly been instructed by The Glorious Qur’an and the Honorable Prophetic Sayings (Hadith). This paper focuses on the prohibition of close relative mating or incest (inbreeding) as well as encouraging breast-feeding and prohibition of marriages between close breast-fed-relatives.


Genetic explanations and updated discoveries are supporting the Islamic instructions in these issues. The deleterious effects of inbreeding (e.g. purifying of bad alleles) as well as the meta-feeding qualities of breast milk are detailed. Such qualities are linked to the prohibition of marriage of breast-fed relatives.


Genetics demonstrate the precedence of Islam to new scientific discoveries and represent therefore, another demonstration of the authenticity of the Islamic scripts. This matching of science and religion can be investigated furthermore in diverse aspects relevant to inbreeding, breast-feeding and prohibition of marriages between close breast-fed-relatives. These aspects are outlined in "Conclusions and Perspectives".
