Allah swt says:
And among His Signs is this, that He created for you wives from among yourselves, that you may find repose in them, and He has put between you affection and mercy. Verily, in that are indeed signs for a people who reflect. (Ar-Rum 30:21)
Unluckily this ability has been abused by human beings to seek pleasure unacceptable by both Allah and humanity.The situation has not been limited to misuse of this power .Many people have been trying to legalize extramarital acts like zina and sodomy in Muslim lands and different articles are being written in English news papers in favour of homosexuality.It is being written in these articles that only religious fanatics are raising voice against sexual and moral crimes where as in reality there is no ruling in Religious scriptures and Quran about these acts.
Allah swt and His Rasool salal laho aliehi wasalam have recommended immediate marriages after puberty and allowed polygamy to keep human beings in discipline but there is no room for moral corruption of any kind .and Allah and His Rasool salal laho aliehi wasalam have always condemned extra marital relationships.
On one instance Allah swt says:
And come not near to the unlawful sexual intercourse. Verily, it is a Fâhishah [i.e. anything that transgresses its limits (a great sin)], and an evil way (that leads one to Hell unless Allâh forgives him). (Al-Isra 17:32)
This violation and abuse is not only limited to zina or fornication .Allah swt has condemned all kind of extramarital activities like homosexuality and masturbation
Allah swt says:
And those who guard their chastity (i.e. private parts, from illegal sexual acts) Except from their wives or (the captives and slaves) that their right hands possess, for then, they are free from blame; But whoever seeks beyond that, then those are the transgressors; (Al-Mu'minun 23:5-7)
The phrase “Whoever seeks beyond that” includes every kind of extramarital activities.
Allah swt has condemned heinous act of homosexuality on many occasions and tribe of Sodom was eliminated for this heinous and even wife of Lot aliehis salam was hit by torment of Allah swt because she was favouring this wrong act.
Here is one of those instances mentioned in Holy Quran:
The prople of Lout (Lot) (those dwelt in the towns of Sodom in Palestine) belied the Messengers When their brother Lout (Lot) said to them: "Will you not fear Allâh and obey Him? "Verily! I am a trustworthy Messenger to you. "So fear Allâh, keep your duty to Him, and obey me. "No reward do I ask of you for it (my Message of Islâmic Monotheism), my reward is only from the Lord of the 'Alamîn (mankind, jinns and all that exists). "Go you in unto the males of the 'Alamîn (mankind) "And leave those whom Allâh has created for you to be your wives? Nay, you are a trespassing people!" They said: "If you cease not. O Lout (Lot)! Verily, you will be one of those who are driven out!" He said: "I am, indeed, of those who disapprove with severe anger and fury your (this evil) action (of sodomy). "My Lord! Save me and my family from what they do." So We saved him and his family, all, Except an old woman (his wife) among those who remained behind. Then afterward We destroyed the others. And We rained on them a rain (of torment). And how evil was the rain of those who had been warned. Verily, in this is indeed a sign, yet most of them are not believers. (Ash-Shu'ara 26:160-174)
Allah swt has declared severe penalties against adulterers and those committing homosexual acts
Allah swt says:
The woman and the man guilty of illegal sexual intercourse, flog each of them with a hundred stripes. Let not pity withhold you in their case, in a punishment prescribed by Allâh, if you believe in Allâh and the Last Day. And let a party of the believers witness their punishment. (This punishment is for unmarried persons guilty of the above crime but if married persons commit it, the punishment is to stone them to death, according to Allâh's Law). (An-Nur 24:2)
On another instance Allah swt says:
And as for those who are guilty of an indecency from among your women, call to witnesses against them four (witnesses) from among you; then if they bear witness confine them to the houses until death takes them away or Allah opens some way for them. And as for the two who are guilty of indecency from among you, give them both a punishment; then if they repent and amend, turn aside from them; surely Allah is oft-returning (to mercy), the Merciful. (An-Nisa 4:15)
Rasool sala laho aliehi wasalam said : "Learn this from me. Allah opens some way for them, both in the case of a married man and a married woman and that of an unmarried man and an unmarried woman. For the married, one hundred lashes and stoning, and for the unmarried one hundred lashes and exile for a year. (Muslim vol. 3, p. 911, no. 4192)
And on another instance Allah swt says:
And the two persons among you who commit illegal sexual intercourse, punish them both. And if they repent (promise Allâh that they will never repeat, i.e. commit illegal sexual intercourse and other similar sins) and do righteous good deeds, leave them alone. Surely, Allâh is Ever the One Who accepts repentance, (and He is) Most Merciful. (An-Nisa 4:16)
And yet on another instance Allah swt says:
This verse clearly indicates that all those involved in illegal sexual acts deserve severe punishments.
According to hadiths of Holy prophet .People who are involved in sodomy whether married or unmarried deserve death penalty.
Muhammad salal laho aliehi wasalam said : "Whoever you find committing the sin of the people of Lut, kill them, both the one who does it and the one to whom it is done.(Sunan Al Tirmidhi)
These acts have also been condemned in Bible on different ocassionsSome of these instances are as follow:
You shall not commit adultery.(Exodus 20:14,New International Version )
But a man who commits adultery lacks judgment; whoever does so destroys himself." (Proverbs 6:32, New International Version)
Do not lie with a man as one lies with a woman; that is detestable. (Leviticus 18:22, New International Version)
The punishment of these wrong act has been mentioned in Bible in the following way:
"If a man is found sleeping with another man's wife, both the man who slept with her and the woman must die." (Deuteronomy 22:22 , New International Version)
"If a man commits adultery with another man's wife--with the wife of his neighbor--both the adulterer and the adulteress must be put to death." (Leviticus 20:10 , New International Version)
And the daughter of any priest, if she profane herself by playing the whore, she profaneth her father: she shall be burnt with fire.( Leviticus 21:9 ,New International Version)
If a man lies with a man as one lies with a woman, both of them have done what is detestable. They must be put to death; their blood will be on their own heads. (Leviticus 20:13, New International version)
From all the above discussion it has been proved that punishment of zina and homosexuality is not against humanity and basic human rights. It is indeed a violation of laws revealed by Allah swt in Holy scriptures and Quran .May Allah save us all from defending these heinous crimes.
