3.2.4 - Muslim responses to genetic engineering

The Ethical Issue

Genetic engineering means deliberately altering genetic material in an organism. In human medicine, genetic engineering includes gene therapy and genome editing. Genetic testing is a related diagnostic practice; it analyses genetic information without itself engineering or altering it. Genetic testing identifies inherited risks; gene therapy aims to treat disease by changing or replacing faulty genetic material; genome editing, such as CRISPR-based editing, aims to make targeted changes in DNA. The ethical issue is not simply "science versus Islam." It is whether humans may use knowledge of creation to prevent harm and treat disease, and where intervention becomes unsafe, unjust, dehumanising or an arrogant attempt to redesign what Allah has entrusted to human beings.

A strong answer should avoid two mistakes. The first mistake is to say that Islam rejects genetic engineering because it "changes Allah's creation." That is too simple. Muslims routinely accept many bodily interventions, including surgery, vaccination and treatment, when they preserve life and prevent harm. The second mistake is to say that Islam accepts genetic engineering because it may cure disease. That is also too simple. Muslim jurists ask about intention, means, risk, consent, lineage, justice, dignity and whether the intervention remains inside Shari'ah limits.

The central distinction is between a scientific possibility and an Islamic moral judgement. Science may show that a gene can be edited. Islamic ethics asks whether it should be edited, by whom, for what purpose, with what risk, and with what effect on the person, family and community.

This is why the AQA wording says "different Muslim responses." The differences are not random opinions. They arise because Muslims may share broad principles but weigh the evidence, risks and purposes differently.

Sources And Method

Muslim bioethics begins from sources of wisdom and authority, but it also uses juristic reasoning because modern genetics is not named directly in the Qur'an or early hadith collections. The Qur'an can support both caution and medical benefit. Qur’an 5:32 states an injunction addressed to the Children of Israel in the context following the story of Adam’s sons. Muslim bioethical discussions apply its emphasis on saving life more widely; it is not a direct ruling on genome editing. Qur'an 4:119 is sometimes used as a warning against corruptly altering Allah's creation. These two source moves create the central tension: treatment may preserve life, but reckless or vain alteration may corrupt a trust.

Hadith can also support treatment. Sunan Abi Dawud 3855 says that people should seek medical treatment because Allah has not made a disease without appointing a remedy, except old age. Used carefully, this supports the search for cures, including cures for inherited disease. It does not automatically approve every experimental procedure, because the same Islamic tradition also requires avoidance of harm and obedience to moral limits.

The method matters. A Muslim jurist or fatwa council does not normally move straight from one verse to a simple yes/no answer. The reasoning often includes:

The important AO1 point is that Islamic bioethics is both text-based and method-based. It is text-based because Qur'an and Sunna provide moral authority. It is method-based because applying those sources to genetics requires interpretation, scientific expertise and judgement about consequences.

Treatment, Enhancement And Lineage

Most Muslim bioethical reasoning becomes clearer when three distinctions are made: treatment versus enhancement, somatic versus germline intervention, and family lineage versus third-party genetic contribution.

Treatment aims to restore health or prevent serious disease. This is the easiest case for permissive Muslim reasoning because it can be linked to preservation of life and the religious duty to seek beneficial knowledge. For example, if a therapy edits cells in a patient with a serious inherited blood disorder, the intention is medical treatment, the benefit is concrete, and the edited cells affect the treated patient rather than future generations. Many Muslim scholars would still require safety, consent, medical expertise and avoidance of exploitation, but the basic aim is morally strong.

Enhancement aims to improve traits where there is no disease, such as height, appearance, athletic ability or intelligence. This is much more controversial. A permissive minority might argue that knowledge is a gift from Allah and that responsible improvement is not inherently wrong. However, major institutional rulings have generally rejected genetic enhancement because it risks vanity, inequality, abuse of human dignity and tampering with the human form without necessity. In A-level terms, enhancement is weaker than treatment because it has less need and more risk of turning human beings into products.

Somatic intervention affects only the treated person's non-reproductive cells. Germline intervention changes sperm, eggs, embryos or early developmental cells in ways that may be inherited. This difference is ethically important because germline editing may affect future people who cannot consent and because mistakes may be passed on. Muslim discussion often treats somatic therapy as more acceptable and germline editing as requiring much stronger caution.

Lineage is a distinct Islamic concern. Hifz al-nasl, the protection of progeny or lineage, means that reproductive technologies are judged not only by health benefit but also by whether they confuse parentage. This is why some Muslim rulings are especially cautious about mitochondrial transfer or reproductive techniques involving third-party genetic material. The concern is not anti-science; it is that family identity, inheritance, marriage rules and social responsibility are protected in Islamic law.
