Episode 7: The genetic effect of marriage between relatives (1/5)
A - (Marry afar and do not become sickly) (1).
B - (Do not marry a close relation, for your offspring will be emaciated) (2).
The first statement is in Al-Harbi’s Ghareeb Al-Hadeeth. He said: «They considered that the son of a man from the daughter of his uncle (his cousin), will turn small and weak, and if she was a stranger (to the family), this was stronger for her son and taller. From thence he said: (Marry afar and do not become sickly), meaning: marry non-relatives, and do not become sickly: bear emaciated and thin children» (3).
Al-‘Iraqi reported from Ibn Salah that he said: I did not find a dependable source for it. Then he said: It is rather known of the statements of Omar, when he said to the Al Assaanib family: (you have become sickly, so marry non-relatives) narrated by Ibrahim Al-Harbi in ‘Ghareeb Al-Hadeeth’, and said: it means marry non-relatives and said: “It is said: (Marry afar and do not become sickly)” (4). (End of quote).
Al-Haafidh said: Ibrahim Al-Harbi narrated in Ghareeb Al-Hadeeth: according to Abdullah bin Al-Mu’ammal, from Ibn Abi Maleekah, he said: Omar said to the Al Assaanib... (5). (End of quote).
And Abdullah bin Al-Mu’ammal is Al-Makhzoumi, (weak) (6).
These texts, (a) and (b), were inferred by a large number of physicians and writers, including: Dr. Mahmoud Nazim Al Nasimi in his book (Prophetic Medicine and Modern Science) (7), Dr. Mohammed Ali Al Baarr in his book (Is there a Prophetic Medicine) and (The Concise in Embryology) (8), Dr. Hamed Ahmed Hamed in his book (Journey of Faith in the Human Body) (9), Al-Hafiz Yusuf Musa in his book (Sex Between Islam and Secularism) (10), Abdullah Naasih ‘Alwan in his book (Raising Children in Islam) (11), Mohamed Kaamil Abdussamad in his book (Scientific Miracles in Islam – The Sunnah) (12) and Dr. Samia Hassan Assa’aati in her book (Marriage Choice and Social Change) (13).
Those who made inference to text (a) were Dr. Khaalis Chalabi in his book (Medicine: A Platform for Faith) (14), Dr. Mohammed Ali Al Baarr in his book (Women’s Work in the Balance) (15), Dr. Abdulhamid Diab and Dr. Ahmed Kerkoz in their book (With Medicine in the Quran) (16), Dr. ‘Izzaddin Faraaj in his book (Islam and Prevention from Disease) (17), and Dr. Omar Al Alfi (18) all of them agree that these two statements are in agreement with what genetics uncovered; that consanguineous marriage leads to diseases and damages, which affect the progeny.
Some of them summed up the discourse - he said: Consanguineous marriage leads to meagreness of the offspring and their weaknesses – and some of them elaborated, but before quoting the words of some of them, we recall that the embryo consists of the fusion of the sperm - which carries (23) chromosomes - with the egg – which carries the same number of chromosomes, and these chromosomes carry a huge number of genetic characteristics (19).
These genetic characteristics are divided into: prevalent characteristics: i.e. able to appear on the foetus, and receding characteristics: i.e. weak and do not appear alone on the foetus, except when two of them align; this is to mean like the weak Statement which is accessible to setting right.
