what Islam says:
“Pre-marital sex is absolutely forbidden in Islam, no matter whether it is with a girl-friend or a prostitute. Pre-marital sex is fornication (zina)”
Allah says:Do not go near adultery, .surely it is an indecency, and an evil way [of fulfilling sexual urge].(17:32) Fornication and adultery have severely been condemned in the saying of the Prophet and the Imams. In Islam, pre-marital sex is considered an immoral act against the rights of Allah and one’s own sexual organs.
Pre-marital sex is a sin punishable by the Islamic court. If an unmarried man and an unmarried woman are found guilty of fornication in an Islamic court, their punishment will be as the following:The woman and the man who fornicate scourge each of them a hundred whips; and in the matter of God s religion, let no tenderness for them seize you if you believe in God and the Last Day; and let a party of the believers witness their punishment.(24:2) If the unmarried man or woman commit fornication more than once, then they will be punished three times by hundred wipes, and if they are proven guilty for the fourth time, then they will be put to death. (As for adultery, its punishment is even more severe because married persons have no excuse, whatsoever, to commit adultery. The shari’ah says that married persons guilty of adultery should be stoned to death)
