Lot:
Homosexuality Condemned
[7:80] Lot said to his people, “You commit such an abomination; no one in the world has done it before!
[7:81] “You practice sex with the men, instead of the women. Indeed, you are a transgressing people.”
[7:82] His people responded by saying, “Evict them from your town. They are people who wish to be pure.”
[7:83] Consequently, we saved him and his family, but not his wife; she was with the doomed.
[7:84] We showered them with a certain shower; note the consequences for the guilty.
Homosexuality Condemned
[11:77] When our messengers went to Lot, they were mistreated, and he was embarrassed by their presence. He said, “This is a difficult day.”
[11:78] His people came rushing; they had grown accustomed to their sinful acts. He said, “O my people, it would be purer for you, if you take my daughters instead. You shall reverence GOD; do not embarrass me with my guests. Have you not one reasonable man among you?”
[11:79] They said, “You know well that we have no need for your daughters; you know exactly what we want.”
[11:80] He said, “I wish I were strong enough, or had a powerful ally!”
[11:81] (The angels) said, “O Lot, we are your Lord’s messengers, and these people cannot touch you. You shall leave with your family during the night, and let not anyone of you look back, except your wife; she is condemned along with those who are condemned. Their appointed time is the morning. Is not the morning soon enough?”
Sodom & Gomorrah Destroyed
[11:82] When our judgment came, we turned it upside down, and we showered it with hard, devastating rocks.
[11:83] Such rocks were designated by your Lord to strike the transgressors.
[11:89] “And, O my people, do not be provoked by your opposition to me into incurring the same disasters as the people of Noah, or the people of Hûd, or the people of Sãleh; and the people of Lot are not too far from you.
[21:71] We saved him, and we saved Lot, to the land that we blessed for all the people.
Lot
[21:74] As for Lot, we granted him wisdom and knowledge, and we saved him from the community that practiced abominations; they were wicked and evil people.
[21:75] We admitted him into our mercy, for he was righteous.
[22:43] Also the people of Abraham, and the people of Lot.
Lot
[26:160] The people of Lot disbelieved the messengers.
[26:161] Their brother Lot said to them, “Would you not be righteous?
[26:162] “I am an honest messenger to you.
[26:163] “You shall reverence GOD, and obey me.
[26:164] “I do not ask you for any wage; my wage comes only from the Lord of the universe.
[26:165] “Do you have sex with the males, of all the people?
[26:166] “You forsake the wives that your Lord has created for you! Indeed, you are transgressing people.”
[26:167] They said, “Unless you refrain, O Lot, you will be banished.”
[26:168] He said, “I deplore your actions.”
[26:169] “My Lord, save me and my family from their works.”
[26:170] We saved him and all his family.
[26:171] But not the old woman; she was doomed.
[26:172] We then destroyed the others.
[26:173] We showered them with a miserable shower; what a terrible shower for those who had been warned!
Lot
[27:54] Lot said to his people, “How could you commit such an abomination, publicly, while you see?
[27:55] “You practice sex with the men, lustfully, instead of the women. Indeed, you are ignorant people.”
[27:56] The only response from his people was their saying, “Banish Lot’s family from your town; they are people who wish to be pure.”
[27:57] Consequently, we saved him and his family, except his wife; we counted her among the doomed.
[27:58] We showered them with a certain shower. It was a miserable shower upon people who had been warned.
[29:26] Lot believed with him and said, “I am emigrating to my Lord. He is the Almighty, the Most Wise.”
Lot
[29:28] Lot said to his people, “You commit such an abomination, no one in the world has ever done it before you.
[29:29] “You practice sex with the men, you commit highway robbery, and you allow all kinds of vice in your society.” The only response from his people was to say, “Bring to us GOD’s retribution, if you are truthful.”
[29:30] He said, “My Lord, grant me victory over these wicked people.”
Angels Visit Abraham and Lot
[29:31] When our messengers went to Abraham with good news (about Isaac’s birth), they also said, “We are on our way to annihilate the people of that town (Sodom), for its people have been wicked.”
[29:32] He said, “But Lot is living there.” They said, “We are fully aware of everyone who lives in it. We will of course save him and his family, except his wife; she is doomed.”
[29:33] When our messengers arrived at Lot’s place, they were mistreated, and he was embarrassed by their presence. But they said, “Have no fear, and do not worry. We will save you and your family, except your wife; she is doomed.
[29:34] “We will pour upon the people of this town a disaster from the sky, as a consequence of their wickedness.”
[29:35] We left standing some of their ruins, to serve as a profound lesson for people who understand.
Lot
[37:133] Lot was one of the messengers.
[37:134] We saved him and all his family.
[37:135] Only the old woman was doomed.
[37:136] We annihilated all the others.
[37:137] You still pass by their ruins by day.
[37:138] And by night. Would you understand?
[38:13] Also, Thamoud, the people of Lot, the dwellers of the Woods (of Midyan); those were the opponents.
[50:13] And `Ãd, Pharaoh, and the brethren of Lot.
[54:33] The people of Lot rejected the warnings.
[54:34] We showered them with rocks. Only Lot’s family was saved at dawn.
[54:35] We blessed him and his family; we thus reward the appreciative.
[54:36] He warned them about our requital, but they ridiculed the warnings.
[54:37] They negotiated with him about his guests; we blinded them. Suffer My retribution; you have been warned.
[54:38] Early the next morning, a devastating retribution struck them.
[25:40] They have passed by the community that was showered with a miserable shower (Sodom). Did they not see it? The fact is, they never believed in resurrection.

[53:53] The evil communities (of Sodom and Gomorrah) were the lowliest. 
[53:54] Consequently, they utterly vanished.

Even the act of condoning Homosexuality is condemned by God. 

[8:25] Beware of a retribution that may not be limited to the evildoers among you.* You should know that GOD’s retribution is severe.

*8:25 A community that tolerates homosexuality, for example, may be hit by an earthquake.

May God save us – our societies and our communities from such an abominable act that rightfully  deserves God’s retribution.
