Alsalamu Alaykum

If I want to answer your question briefly, just I can say that you are allowed to do that. however for more explanation, I’d rather refer you to the following verse.Allah (SWT) says in the holy Quran:


حُرِّمَتْ عَلَيْكُمْ أُمَّهَاتُكُمْ وَبَنَاتُكُمْ وَأَخَوَاتُكُمْ وَعَمَّاتُكُمْ وَخَالَاتُكُمْ وَبَنَاتُ الْأَخِ وَبَنَاتُ الْأُخْتِ وَأُمَّهَاتُكُمُ اللَّاتِي أَرْضَعْنَكُمْ وَأَخَوَاتُكُم مِّنَ الرَّضَاعَةِ وَأُمَّهَاتُ نِسَائِكُمْ وَرَبَائِبُكُمُ اللَّاتِي فِي حُجُورِكُم مِّن نِّسَائِكُمُ اللَّاتِي دَخَلْتُم بِهِنَّ فَإِن لَّمْ تَكُونُوا دَخَلْتُم بِهِنَّ فَلَا جُنَاحَ عَلَيْكُمْ وَحَلَائِلُ أَبْنَائِكُمُ الَّذِينَ مِنْ أَصْلَابِكُمْ وَأَن تَجْمَعُوا بَيْنَ الْأُخْتَيْنِ إِلَّا مَا قَدْ سَلَفَ إِنَّ اللَّـهَ كَانَ غَفُورًا رَّحِيمًا

Forbidden to you are your mothers, your daughters and your sisters, your paternal aunts and your maternal aunts, your brother’s daughters and your sister’s daughters, your [foster-]mothers who have suckled you and your sisters through fosterage, your wives’ mothers, and your stepdaughters who are under your care [born] of the wives whom you have gone into—but if you have not gone into them there is no sin upon you—and the wives of your sons who are from your own loins, and that you should marry two sisters at one time—excluding what is already past; indeed Allah is all-forgiving, all-merciful. [1]




According to Islamic rules, a man is not permitted to marry those who are Mahram to him. Their names and relations are expressed in the verse. Therefore, a man is allowed to marry those whose names are not expressed in the verse. As a result,you are allowed to marry your father's uncle daughter.

Father's uncle's daughter is a second cousin, right? That's allowed. The genetic risk associated with marrying close family is not usually that significant if the cousin marriage is a one-off thing. The risk is increased by multiple generations of close relative marriage. 

A second cousin is not as closely related as a first cousin, and even first cousin marriage is permitted. 

Or is this a first cousin once removed? I'm not sure how the terminology works. Either way, it's allowed.

I advise you not to marry your family since they cause birth defects and higher than expected rates of deaths and congenital abnormalities in the babies. Couples with close genes are at risk of having a child with an autosomal recessive condition. This is obviously a sign from Allah that it is not recommended. I may be wrong. But its your choice brother.

Imam al-Baqir's parents were cousins, so obviously there is nothing wrong with one-off cousin marriages.

4 minutes ago, Shaykh Patience101 said:

Is it possible that there is a higher chance of genetic abnormalities with cousin marriages now, then there were in the middle of Arabia 1400 years ago? Are there any significant genetic differences?

This is a legitimate question on my part.

It is unlikely, but I've never seen any comparative studies. A larger population should mean more genetic diversity, and more diversity means less risk of concentration of genetic defects. 


On the other hand, people are much more likely to survive genetic defects and pass them on to their offspring nowadays.
