The Qur'an on Sodom

And there came two angels to Sodom at even; and Lot sat in the gate of Sodom: and Lot seeing them rose up to meet them; and he bowed himself with his face toward the ground;
And he said, Behold now, my lords, turn in, I pray you, into your servant's house, and tarry all night, and wash your feet, and ye shall rise up early, and go on your ways. And they said, Nay; but we will abide in the street all night.
And he pressed upon them greatly; and they turned in unto him, and entered into his house; and he made them a feast, and did bake unleavened bread, and they did eat.
But before they lay down, the men of the city, even the men of Sodom, compassed the house round, both old and young, all the people from every quarter:
And they called unto Lot, and said unto him, Where are the men which came in to thee this night? bring them out unto us, that we may know them.
And Lot went out at the door unto them, and shut the door after him,
And said, I pray you, brethren, do not so wickedly.
Behold now, I have two daughters which have not known man; let me, I pray you, bring them out unto you, and do ye to them as is good in your eyes: only unto these men do nothing; for therefore came they under the shadow of my roof.
And they said, Stand back. And they said again, This one fellow came in to sojourn, and he will needs be a judge: now will we deal worse with thee, than with them. And they pressed sore upon the man, even Lot, and came near to break the door.
But the men put forth their hand, and pulled Lot into the house to them, and shut to the door.
And they smote the men that were at the door of the house with blindness, both small and great: so that they wearied themselves to find the door.
And the men said unto Lot, Hast thou here any besides? son in law, and thy sons, and thy daughters, and whatsoever thou hast in the city, bring them out of this place:
For we will destroy this place, because the cry of them is waxen great before the face of the Lord; and the Lord hath sent us to destroy it.
And Lot went out, and spake unto his sons in law, which married his daughters, and said, Up, get you out of this place; for the Lord will destroy this city. But he seemed as one that mocked unto his sons in law.
And when the morning arose, then the angels hastened Lot, saying, Arise, take thy wife, and thy two daughters, which are here; lest thou be consumed in the iniquity of the city.
And while he lingered, the men laid hold upon his hand, and upon the hand of his wife, and upon the hand of his two daughters; the Lord being merciful unto him: and they brought him forth, and set him without the city.
And it came to pass, when they had brought them forth abroad, that he said, Escape for thy life; look not behind thee, neither stay thou in all the plain; escape to the mountain, lest thou be consumed.
And Lot said unto them, Oh, not so, my Lord:
Behold now, thy servant hath found grace in thy sight, and thou hast magnified thy mercy, which thou hast shewed unto me in saving my life; and I cannot escape to the mountain, lest some evil take me, and I die:
Behold now, this city is near to flee unto, and it is a little one: Oh, let me escape thither, (is it not a little one?) and my soul shall live.
And he said unto him, See, I have accepted thee concerning this thing also, that I will not overthrow this city, for the which thou hast spoken.
Haste thee, escape thither; for I cannot do anything till thou be come thither. Therefore the name of the city was called Zoar.
The sun was risen upon the earth when Lot entered into Zoar.
Then the Lord rained upon Sodom and upon Gomorrah brimstone and fire from the Lord out of heaven;
And he overthrew those cities, and all the plain, and all the inhabitants of the cities, and that which grew upon the ground. Genesis 19: 1-25

It isn't just the Bible that condemns homosexual acts. The Qur'an makes several references to Sodom. The following passages are from the Abdullah Yusuf Ali translation of the Qur'an (Lut is the Qur'anic rendition of Lot):

We also (sent) Lut: He said to his people: "Do ye commit lewdness such as no people in creation (ever) committed before you?
"For ye practise your lusts on men in preference to women : ye are indeed a people transgressing beyond bounds."
And his people gave no answer but this: they said, "Drive them out of your city: these are indeed men who want to be clean and pure!"
But we saved him and his family, except his wife: she was of those who legged behind.
And we rained down on them a shower (of brimstone): Then see what was the end of those who indulged in sin and crime! Surah 7 (Al-Araf): 80-84

When Our messengers came to Lut, he was grieved on their account and felt himself powerless (to protect) them. He said: "This is a distressful day."
And his people came rushing towards him, and they had been long in the habit of practising abominations. He said: "O my people! Here are my daughters: they are purer for you (if ye marry)! Now fear Allah, and cover me not with shame about my guests! Is there not among you a single right-minded man?"
They said: "Well dost thou know we have no need of thy daughters: indeed thou knowest quite well what we want!"
He said: "Would that I had power to suppress you or that I could betake myself to some powerful support."
(The Messengers) said: "O Lut! We are Messengers from thy Lord! By no means shall they reach thee! Now travel with thy family while yet a part of the night remains, and let not any of you look back; but thy wife (will remain behind): To her will happen what happens to the people. Morning is their time appointed: Is not the morning nigh?"
When Our Decree issued, We turned (the cities) upside down, and rained down on them brimstones hard as baked clay, spread, layer on layer,-
Marked as from thy Lord: Nor are they ever far from those who do wrong! Surah 11 (Hud): 77-83

The people of Lut rejected the apostles.
Behold, their brother Lut said to them: "Will ye not fear (Allah)?
"I am to you an apostle worthy of all trust.
"So fear Allah and obey me.
"No reward do I ask of you for it: my reward is only from the lord of the Worlds.
"Of all the creatures in the world, will ye approach males,
"And leave those whom Allah has created for you to be your mates? Nay, ye are a people transgressing (all limits)!"
They said: "If thou desist not, O Lut! thou wilt assuredly be cast out!"
He said: "I do detest your doings."
"O my Lord! deliver me and my family from such things as they do!"
So We delivered him and his family, all.
Except an old woman who lingered behind.
But the rest We destroyed utterly.
We rained down on them a shower (of brimstone): and evil was the shower on those who were admonished (but heeded not)! Surah 26 (Ash-Shuara): 160-173

(We also sent) Lut (as an apostle): behold, He said to his people, "Do ye do what is shameful though ye see (its iniquity)?
Would ye really approach men in your lusts rather than women? Nay, ye are a people (grossly) ignorant!
But his people gave no other answer but this: they said, "Drive out the followers of Lut from your city: these are indeed men who want to be clean and pure!"
But We saved him and his family, except his wife; her We destined to be of those who lagged behind.
And We rained down on them a shower (of brimstone): and evil was the shower on those who were admonished (but heeded not)! Surah 27 (An-Nami): 54-58

And (remember) Lut: behold, he said to his people: "Ye do commit lewdness, such as no people in Creation (ever) committed before you.
"Do ye indeed approach men, and cut off the highway?- and practise wickedness (even) in your councils?" But his people gave no answer but this: they said: "Bring us the Wrath of Allah if thou tellest the truth."
He said: "O my Lord! help Thou me against people who do mischief!"
When Our Messengers came to Abraham with the good news, they said: "We are indeed going to destroy the people of this township: for truly they are (addicted to) crime."
He said: "But there is Lut there." They said: "Well do we know who is there : we will certainly save him and his following,- except his wife: she is of those who lag behind!"
And when Our Messengers came to Lut, he was grieved on their account, and felt himself powerless (to protect) them: but they said: "Fear thou not, nor grieve: we are (here) to save thee and thy following, except thy wife: she is of those who lag behind.
"For we are going to bring down on the people of this township a Punishment from heaven, because they have been wickedly rebellious." Surah 29 (Al-Ankaboot) 28-34
