Assalaamu alaykum. According to Islam, what is the ruling on providing medical treatment to homosexuals as a doctor? Please also provide sources of evidence from the Quran and Hadith.

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.

Homosexuality is an outrageous act, and if someone does it out of his own free after having reached puberty, then, Islamically, he deserves to be killed regardless of whether he is the doer or the one to whom it is done.

Shaykh Ibn Taymiyyah said, “The one who commits homosexuality and the one to whom it is done must both be stoned to death regardless of whether they are married or unmarried, as it was reported in the Sunan that the Prophet, sallallaahu ʻalayhi wa sallam, said, 'Whoever you find engaging in the practices of the people of Loot (Lut), kill the one who does it and the one to whom it is done,' and the Companions unanimously agreed that whoever engages in homosexuality must be killed.”

Since they both deserve to be killed Islamically, then their blood is not sacred, and, without a doubt, providing medication and treatment for them is an act of sympathy towards them and giving them a chance in life that they do not deserve.

The scholars of Fiqh stated that if a person has enough water for ablution only and then finds a thirsty person, he should give him the water and perform Tayammum (dry ablution), unless the blood of this thirsty person is not sacred, then he does not give him the water even if he is thirsty and dying.

Al-Hattaab from the Maaliki School of jurisprudence said, “What is understood from Ibn Abdus-Salaam's restriction of the ruling to the human whose blood is sacred is that the belligerent non-Muslim, the apostate, the adulterer [the person who is married and fornicates] and the like, then fear for their life when they are thirsty is not taken into consideration, and this is the apparent view if proof is established.”

Therefore, to conclude, the person whose blood is not sacred, one should not extend a helping hand to them in treating them because they do not deserve life.

Allaah knows best.
