No doubt that in Islam, homosexuality is sinful and shameful. In Islamic terminology it is called fahsha’ or an atrocious and obscene act. Islam teaches that believers should neither do obscene acts, nor in any way indulge in their propagation. Allah says, “Those who love (to see) obscenity published broadcast among the Believers will have a grievous Penalty in this life and in the Hereafter: Allah knows, and you know not.” (Al-Nur: 19)
There is consensus among all Muslim scholars both in past and present times that homosexuality is a prohibited act because it is an assault on the humanity of a person, destruction of the family, and a clash with the aims of the Divine Legislator, one of which is the establishment of sexual instincts between males and females so as to encourage the institution of marriage and procreation.
Sheikh Ahmad Kutty, a senior lecturer and Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states: “One is not allowed in Islam to attend a so-called marriage ceremony between homosexuals. By “marrying” so, those people are waging an open war against Allah Almighty.
Remember, homosexuality is the most heinous sin because of which Allah destroyed an entire nation. So, one should never attend such a ceremony.
