Answer

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

 

We are not aware of any Prophetic narration about the superiority of marrying cousins, and the principle in choosing one’s spouse in general is religion and good moral conduct, as confirmed in religious texts and this is clarified in Fataawa 86667 and 84221.

It should be mentioned that some narrations have been reported about the dislikeability of marrying relatives but these narrations are not authentic. However, some scholars  may  Allaah  have  mercy  upon  them are of the opinion that it is disliked to marry relatives based on these inauthentic narrations.

Nonetheless, some medical studies showed that marrying relatives may lead to the transfer of some hereditary diseases. However, this is not true all the time. The medical studies which were carried out recently stated that the danger of the spouses who are relatives having children with deformations or hereditary diseases reaches 7% or 8%, whereas the percentage in spouses who are not relatives is only 5%.

This study advised doctors not to immediately discourage relatives from marrying each other, and that instead they should advise them to carry out medical tests before marriage.

It is worth mentioning here that marrying relatives is absolutely permissible and there is no general harm in it. It is impossible for Allaah to render something absolutely permissible, which would be a general harm for all people.

Allaah Knows best.
