In the Qur’ân, Allah tells us that homosexuality is forbidden practice. Allah says: “The inhabitants of the city came in joy (at the news of the young men). Lot said: ‘These are my guests. Disgrace me not. But fear Allah and shame me not.’ They said: ‘Did we not forbid you from entertaining others?.’ He said: ‘These are my daughters, if you must act.’ Verily, by thy life (O Prophet), in their wild intoxication, they wander in distraction, to and fro. But the (mighty) blast overtook them at sunrise. And We turned (the cities) upside down, and rained down on them brimstones hard as baked clay. Behold! In this are signs for those who by tokens do understand” [Sûrah al-Hijr: 72-75]
Allah says: “We also (sent) Lot: he said to his people: “Do ye commit lewdness such as no people in creation (ever) committed before you? For ye practice your lusts on men in preference to women: ye are indeed a people transgressing beyond bounds” [Sûrah al-A`râf: 80-81]
Lot (peace be upon him) condemns them for the evil of their deed and describes it as transgression. Such descriptions are attributes of the deeds themselves. Therefore, it cannot be assumed to be a ruling only for Lot's people and not for later generations. The qualiity evil is attributed to the deed itself, and intrinsic qualities do not change with the coming of another Prophet.
Furthermore, Prophet Muhammad (peace be upon him) made it clear that homosexuality is a sin.
Even if none of this evidence were available, the practice of homosexuality would still be forbidden, simply because Islam expressly forbids any sexual contact outside of marriage.
Allah says: “And those who guard their chastity except with their spouses and those whom their right hands possess, for then they are not blameworthy. But those who seek something beyond this are transgressors.”
This verse clearly delineates the limits of lawful sexual activity.
Allah, in the Qur’ân, also strictly defines whom we can marry. Allah states for the man all the women that he is prohibited to marry and then says that others are permissible, while continuing to refer to those with whom it is lawful by the feminine gender. Therefore, men are restricted to marrying women and women are restricted to marrying men. [Refer to Sûrah al-Nisâ’: 23-25]
It must also be clarified here that the sin is the practice of homosexuality, not a person's inner feelings or desires. A Muslim is rewarded for restraining his or her unlawful desires to please Allah.
And Allah knows best.
