Fornication and the consumption of alcohol and pork are strictly forbidden in Islam, as stated in the central religious text of Islam, the Quran.



O you who have believed, indeed, intoxicants, gambling, [sacrificing on] stone alters [to other than Allah], and divining arrows are but defilement from the work of Satan, so avoid it that you may be successful. Quran 5:90



He has only forbidden to you dead animals, blood, the flesh of swine, and that which has been dedicated to other than Allah . But whoever is forced [by necessity], neither desiring [it] nor transgressing [its limit], there is no sin upon him. Indeed, Allah is Forgiving and Merciful. Quran 2:173



And do not approach unlawful sexual intercourse. Indeed, it is an immoral and evil way. Quran 17:32
