Fornication / Adultery

{17:32} and go not nigh to fornication; surely it is an indecency and an evil way.

{24:30} Say to the believing men that they cast down their looks and guard their private parts; that is purer for them; surely Allah is Aware of what they do.

{24:31} And say to the believing women that they cast down their looks and guard their private parts and do not display their ornaments except what appears thereof, and let them wear their head-coverings over their bosoms, and not display their ornaments except to their husbands or their fathers, or the fathers of their husbands, or their sons, or the sons of their husbands, or their brothers, or their brothers' sons, or their sisters' sons, or their women, or those whom their right hands possess, or the male servants not having need (of women), or the children who have not attained knowledge of what is hidden of women; and let them not strike their feet so that what they hide of their ornaments may be known; and turn to Allah all of you, O believers! So that you may be successful.

{33:59} O Prophet! say to your wives and your daughters and the women of the believers that they let down upon them their over-garments; this will be more proper, that they may be known, and thus they will not be given trouble; and Allah is Forgiving, Merciful.

Comment: The fulfilment of any sexual desire is prohibited outside of marriage.

{24:2} (As for) the fornicatress and the fornicator, flog each of them, (giving) a hundred stripes, and let not pity for them detain you in the matter of obedience to Allah, if you believe in Allah and the last day, and let a party of believers witness their chastisement.

Comment: Capital punishment is prescribed for fornicators and adulterers. The punishment can only be implemented by a qualified Islamic judge in an Islamic state. Four reliable witnesses are required to have seen the act. Public announcement of such sins is prohibited in Islam. Anyone guilty of admitting their sin in public on four separate occasions will also be given the same punishment.

{24:4} And those who accuse free women then do not bring four witnesses, flog them, (giving) eighty stripes, and do not admit any evidence from them ever; and these it is that are the transgressors.

Comment: Falsely accusing chaste women is also a major sin in Islam. Anyone guilty of degrading women in such a manner must also be punished by the Islamic court.
