Sharia teaches that homosexuality is a vile form of fornication, punishable by death.
The shooting massacre of gays in an Orlando nightclub by an Afghan-born Muslim Jihadist Omar Mateen that killed 50 adds to the list of darkest days in recent US history alongside 9/11, Boston Marathon bombing, and the San Bernardino massacre. All of those attacks were carried out by pious Muslims inspired by the teachings of their religion, Islam.
Like in the aftermath of every such Jihadist massacre, media was quick to hide the true motivation behind it, which is the teachings and commands of Islam. CNN immediately put the blame on Mateen’s mental illness. Calling the killer a closet gay, wrote Don Lemon: “some of the people who are radicalized, could be radicalized because they have homosexual tendencies and they’re upset by it.” Media pundits offered almost every conceivable excuse for the massacre but the true one – that Omar Mateen was a Muslim and his religion Islam ordains killing of gays. Allah calls homosexuality the worst sin not even committed by animals (Quran 26:165-166, 7:80-81) and commands Muslims to punish the offenders if they fail to repent: “If two men among you are guilty of lewdness, punish them both. If they repent and amend, Leave them alone…” (Quran 4:16)
Indeed, the Quran judges homosexuality as the most hideous sin, never committed by any other animals, or by even humans and jinn before coming of Islam. And Islam has historically dealt with this worst possible sin with due punishment, death. Murdering gays is also a prophetic tradition (Sunna) in Islam. Hear from the mouth of a pious Islamic scholar, who spoke at an Orlando Mosque in April:
Abu Dawud (4462) - The Messenger of Allah (peace and blessings of Allah be upon him) said, "Whoever you find doing the action of the people of Loot, execute the one who does it and the one to whom it is done."
Abu Dawud (4448) - "If a man who is not married is seized committing sodomy, he will be stoned to death."
Bukhari (72:774) - "The Prophet cursed effeminate men (those men who are in the similitude (assume the manners of women) and those women who assume the manners of men, and he said, 'Turn them out of your houses.' The Prophet turned out such-and-such man, and 'Umar turned out such-and-such woman."
al-Tirmidhi, Sunan 1:152 - [Muhammad said] "Whoever is found conducting himself in the manner of the people of Lot, kill the doer and the receiver."
According to these sayings of Prophet Muhammad (hadiths), homosexuals must be burned alive or have wall pushed on them. Prophet Muhammad’s son-in-law Ali had two people burned, and Abu Bakr [Muhammad's father-in-law] had a wall thrown down on them. (Mishkat 1:765, Prescribed Punishments).
In sum, Omar Mateen killed gays at the Orlando nightclub, because Islam recognizes homosexuality as a hideous sin and urge upon Muslims to punish homosexuals duly. Punishment for homosexuals is death in Islam. Hundreds of gays are hanged in Iran every year. Mateen simply responded to the call to duty of his God and committed the massacre. It was his Jihad in the cause of Allah.
