Aslm ya ikhwanee! Is it permissible to transplant organs of forbidden animals such as pigs. A case study was a successful transplant ( pig heart to human) in USA which seems a breakthrough in medicine. So, what's d ruling as regards D's.

Here is an extract from https://islamqa.info/en/answers/93212/is-it-permissible-to-do-an-operation-on-the-heart-valves-using-pigskin

......
Based on this discussion, medical treatment by means of transplanting an animal organ of this type [i.e., from an impure animal] should meet two conditions:

1-The sick person should be in need of the transplant from the impure animal. This condition is met when specialist doctors testify that there is indeed such a need.

2-No pure organ is available that could be used instead.

If these two conditions are met, then there is nothing wrong with the surgeon transplanting this impure organ or part of it, and the presence of this impure organ in the patient’s body is not regarded as having any effect on his prayer or acts of worship for which purification is required, since there is a reason for which a concession is granted allowing it.

Ahkaam al-Jaraahah al-Tibbiyyah (p. 268).

Hence the Islamic Fiqh Council stated that it is permissible, with no reservations, to take an organ from an animal whose meat is permissible to eat and that has been slaughtered properly, or from another animal in the case of necessity, and transplant it into the person who is in need of that.

Shaykh Muhammad ibn Saalih al-‘Uthaymeen (may Allaah have mercy on him) was asked: The heart doctors may put in a vein made of metal or they may put in a vein that they have taken from a pig. But the metal vein may deteriorate and the veins from the pig may be better, as they may be accepted (by the body) and become like part of the person’s body. What is the ruling on that?

He replied:

There is nothing wrong with it, i.e., there is nothing wrong with putting veins from another animal into a person’s heart, and it should be based on what is most suitable for his heart, because this is not the matter of eating, and Allaah has only forbidden eating pigs, and this is not eating. Once we know that nothing else will help him except this, then it becomes the matter of necessity and Allaah says with regard to eating pig meat, i.e., putting it directly in the mouth (interpretation of the meaning):

“while He has explained to you in detail what is forbidden to you, except under compulsion of necessity”
[al-An’aam 6:119]
