How Islamic Bioethics Navigates Organ Transplantation
Imagine a patient with end-stage kidney disease, whose survival depends on a transplant. For millions of Muslims worldwide, this medical reality presents not just a physical challenge, but a profound religious and ethical question: Does Islamic law permit organ transplantation when it involves manipulating the human body, considered sacred in Islamic tradition? This question lies at the heart of one of modern medicine's most compelling intersections with religious ethics.
The ethical landscape of organ transplantation within Islamic bioethics represents a fascinating journey of intellectual interpretation, where ancient principles meet modern medical necessity. At the center of this discussion stands a pivotal Islamic legal concept: the "maximus of necessity," which recognizes that severe necessity can make permissible what would normally be forbidden.
This principle has become the cornerstone for many Islamic scholars and jurists when evaluating the permissibility of organ donation and transplantation, allowing them to balance the sacredness of the human body against the preservation of human life1 .
The "maximus of necessity" makes permissible what would normally be forbidden under circumstances of severe need.
Islamic scholars balance bodily sanctity against life preservation when evaluating organ transplantation.
In Islamic tradition, the human body is considered a sacred trust from God. The Quran and teachings of Prophet Muhammad explicitly express sanctity to human life and body, considering the desecration of a human body—whether alive or dead—a violation amounting to a great sin. Taking a life without legal justification or inflicting harm, injury, or aggression against an individual is considered an unlawful act1 .
This profound respect for bodily integrity initially led some scholars to question whether organ transplantation could be permissible. However, a more nuanced examination of Islamic legal principles revealed frameworks capable of addressing this modern medical advancement.
The maxim of necessity—a derivative of the broader principle that "necessity makes the prohibited permissible"—has served as the primary bridge between traditional sanctity concerns and contemporary medical needs. This doctrine acknowledges that under circumstances of severe need, normally prohibited acts may become allowable1 .
Islamic jurists apply this principle to organ transplantation by weighing several factors:
"The permissibility of organ donation and transplantation [is] somehow mentioned in the main sources of Islamic law and biomedical ethics" through the application of such principles1 .
While ethical frameworks provide the legal and moral foundation for organ transplantation, scientific advances make the physical process possible. One of the most critical challenges in transplantation is organ preservation—maintaining organs in viable condition between retrieval from the donor and implantation into the recipient.
When organs are removed from the body, they're deprived of oxygenated blood (ischemia), leading to cellular damage that can compromise transplant success. Cold storage has been the traditional method to reduce metabolic demands and attenuate this ischemic injury4 .
Through decades of research, scientists have developed specialized preservation solutions that dramatically improve organ viability. The most widely used include:
Recent research has focused on enhancing these preservation solutions with supplemental compounds to further improve their effectiveness. A 2022 study published in the journal Annals of Transplantation investigated the effects of supplementing standard HTK solution (commercially known as Custodiol) with either nicorandil (a potassium channel opener) or rutin trihydrate (a powerful antioxidant) for kidney preservation.
The research team employed both in vitro experiments using human embryonic kidney cells (HEK-293) and in vivo testing in a rat model of renal ischemia. This dual approach allowed them to examine cellular effects alongside whole-organ function.
Researchers created two modified preservation fluids by supplementing standard HTK solution with either 0.5 mmol/L nicorandil (OPF-NCD) or 0.1 mmol/L rutin trihydrate (OPF-RTT).
Human kidney cells were preserved in these solutions at various temperatures (4°C, 15°C, 25°C, and 37°C) for 4 and 24 hours, then analyzed for several parameters.
Using a rat model of renal ischemia, researchers evaluated the preservation efficacy by monitoring serum creatinine and blood urea nitrogen levels—key indicators of kidney function.
Finally, they examined preserved rat kidney tissues for expression of caspase 3, an apoptotic marker indicating cell death.
The findings demonstrated significant advantages for both supplemented solutions across multiple parameters:
| Parameter | Control (HTK) | Nicorandil-Supplemented | Rutin Trihydrate-Supplemented |
|---|---|---|---|
| ATP Levels | 23,216 ± 1,315 pmol/cell | 32,999 ± 1,454 pmol/cell | Similar to control |
| Reactive Oxygen Species | Baseline | Similar to control | 1.25-fold decrease |
| Cell Viability | Baseline | 4.8-fold increase | 4.8-fold increase |
Data adapted from
The enhanced ATP levels with nicorandil supplementation are particularly significant because ATP serves as the primary energy currency of cells. Higher ATP levels indicate better preserved cellular function during the preservation period. Similarly, the reduction in reactive oxygen species with rutin trihydrate supplementation demonstrates decreased oxidative damage—a key factor in ischemia-reperfusion injury.
| Parameter | Control (HTK) | Nicorandil-Supplemented | Rutin Trihydrate-Supplemented |
|---|---|---|---|
| Serum Creatinine (mg/dL) | Higher than treatment groups | 0.548 ± 0.052 | 0.956 ± 0.043 |
| Blood Urea Nitrogen (mg/dL) | Higher than treatment groups | 85.36 ± 4.64 | 92.85 ± 3.15 |
| Caspase 3 Expression | Baseline | Suppressed | Suppressed |
Data adapted from
The suppressed expression of caspase 3 in both treatment groups indicates reduced programmed cell death, suggesting better tissue preservation. These biochemical findings translated to improved functional outcomes, with both supplemented solutions showing better kidney function markers compared to controls.
Transplantation research relies on specialized materials and reagents. The following table highlights essential components used in the featured experiment and their functions:

Specialized fluids that maintain organ viability during the critical period between retrieval and transplantation.
Compounds that regulate ion channels to improve cellular energy status and reduce damage during preservation.
Substances that neutralize harmful free radicals generated during ischemia-reperfusion injury.
While improved preservation solutions address technical challenges, ethical considerations shape how these advances are implemented. The shortfall in suitable organs has prompted the transplant community to expand acceptance criteria, including increased use of extended criteria donors (such as older donors or those with certain medical conditions) and donation after circulatory death5 9 .
A 2004 study demonstrated that using expanded criteria donor (ECD) kidneys effectively doubled transplant volume within a single center. Through careful donor evaluation and recipient matching, patient and graft survival rates were comparable to those using standard criteria donors9 .
Novel technologies like normothermic machine perfusion (NMP) now allow organs to be maintained at body temperature with oxygenated blood outside the body. This approach not only preserves organs better but enables functional assessment and potential reconditioning before transplantation2 5 .
Recent data from the UNOS/OPTN database analysis showed that using NMP for donation after circulatory death livers significantly reduced discard rates (7.25% with NMP versus 30.52% with traditional cold storage) and improved post-transplant outcomes2 .
The ethical framework surrounding organ transplantation in Islam—and indeed in global bioethics—must balance multiple considerations:
Maximizing successful outcomes and efficient organ allocation
Ensuring fair access to transplantation regardless of social or economic status
Honoring the dignity of both donors and recipients
Respecting diverse belief systems and religious values
Studies examining stakeholder preferences have found that the public, medical professionals, and patients consider multiple factors beyond pure medical success, including "maximum benefit," "social valuation," "moral deservingness," and "fair innings" (prioritizing younger patients)8 .
The journey of organ transplantation through the lens of Islamic bioethics demonstrates the remarkable capacity of both religious and scientific systems to evolve in response to human need. The maxim of necessity has provided a principled foundation for accepting transplantation as a life-saving treatment, while scientific innovations continue to improve its safety and effectiveness.
What makes this convergence particularly compelling is how it reflects a broader human capacity to reconcile apparent contradictions—between bodily sanctity and medical intervention, between traditional principles and contemporary applications. As research continues to enhance our technical abilities through improved preservation solutions, machine perfusion, and personalized approaches, the ethical framework ensures these advances serve fundamental human values and dignity.
Through it all, the ongoing dialogue between scientific innovation and ethical reflection will remain essential to ensuring that the gift of life extends to as many as possible, in accordance with both medical excellence and deeply held values.
