One of the aims of Islamic Sharee’ah is to preserve honor and lineage, so zinaa (unlawful sexual intercourse) is forbidden. Allaah says:
“And do not come near to unlawful sexual intercourse. Verily it is a faahishah (a great sin) and an evil way (that leads to Hell unless Allaah forgives).” [Surah al-Israa’ (17):32]

The sharee’ah blocks all the ways and means that could lead to zinaa, by enjoining hijaab and lowering the gaze, and by forbidding being alone with a non-mahram woman, etc.

A married man who commits adultery is given the worst kind of punishment, which is stoning to death, so that he may taste the results of his deeds and so that every part of his body may suffer just as every part of his body enjoyed the illicit liaison. The fornicator who was previously unmarried is to be punished with the maximum number of lashes mentioned in sharee’ah, which is 100, in addition to the humiliation they face when this punishment is witnessed by the believers and the humiliation of being banished from their city and the scene of the crime for one full year.

In the life of the grave, the punishment for men and women who were guilty of zinaa is that they will be in an oven whose top is narrow and whose bottom is wide, with a fire beneath it, and they will be naked therein. When the heat of the fire increases, they will scream and rise up until they nearly come out of the top, then when the fire decreases, they will fall back down. This will repeated over and over until the onset of the Hour.

What is even worse is when a man continues to commit adultery even when he grows old, death approaches, and Allaah gives him the opportunity to repent. Abu Hurayrah reported that the Prophet Mohammed Pbuh said: “There are three to whom Allaah will not speak on the Day of Resurrection, nor praise, nor look at; theirs will be a painful torment: an old man who commits zinaa, a king who lies, and a poor man who is arrogant,”54

Among the worst of incomes is the earnings of a prostitute which she takes for committing zinaa. A prostitute who earns her living by selling herself is deprived of having her prayers answered when the gates of heaven are opened in the middle of the night.55 Being needy or poor is not an acceptable excuse for transgressing the limits set by Allaah. There is an old saying that a free woman would rather starve than earn a living by breastfeeding, so how about her private parts?

Nowadays, all the doors of immorality have been opened, and the Shaytaan and his supporters have made it very easy for people to commit sin. This has been followed by the spread of tabarruj (wanton display) and unveiling among women, people allowing their gazes to wander to things they should not look at, an increase in mixing between the sexes, the popularity of immoral magazines and lewd films, increased travel to corrupt countries, the establishment of honor, and an increase in the number of illegitimate births and abortions.

O Allaah, we ask you to show us Your mercy and to protect us from immorality; we ask You to purify our hearts and to keep our private parts chaste, and to place a barrier between us and what is haraam.
