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 is His slave and Messenger.
The contemporary scholars have different opinions regarding the ruling of keeping a husband's semen in a semen bank for future use to fertilize his wife's ovum.
Some of them are of the opinion that it is allowed provided the fertilization is completed during the life of the husband. Some other scholars allowed the procedure even after the death of the husband but during the widow's waiting period only.
However, there are some other scholars who are of the view that it is absolutely forbidden to keep the husband's semen.
We at Islamweb adopt the last opinion which is that it is prohibited.
Indeed, the Islamic Fiqh Committee has also passed a resolution prohibiting this act as a way of preventing harm, because there is a high probability for the mixing of semen or its misusage, and this may lead to the intermixing of lineages.
Therefore, fertilizing a wife's ovum with her husband's sperm that is kept in a semen bank after his death is not allowed.
There should be no disagreement on this issue because the end of the marital relationship by the death of the husband is like its end by an irrevocable divorce. In fact, there is no disagreement among the scholars that artificial insemination is not allowed after an irrevocable divorce.
As regards fertilizing the wife's ovum by the semen of her imprisoned husband, then it seems - Allaah Knows best – that it is prohibited, firstly because there is no necessity, and secondly, this may result in committing some prohibitions, such as getting the semen of the husband through forbidden acts, like masturbation, for example. Besides, the wife could be suspected about her chastity and she may be accused. It is also possible that she may get pregnant from someone else and claim that the pregnancy is from her husband's semen; there are many other prohibitions.
With regard to the husband's semen being mixed with that of another man, then if the husband is negligent in following up, then he is sinful but the child is traced back to him due to the possibility that the child may be conceived by his semen.
The Prophet said: "The child is for the owner of the bed (i.e. the husband). [Al-Bukhari and Muslim]
Allaah Knows best.
