Zina is a major sin that also leads to other kinds of sins that come after it. It is surrounded by a host of other sins that come before and after.
Allaah says (interpretation of the meaning):
“And come not near to the unlawful sexual intercourse. Verily, it is a Fahishah [i.e. anything that transgresses its limits (a great sin)], and an evil way (that leads one to Hell unless Allah forgives him).” [ Al-Isra 32]
The Prophet (peace and blessings of Allaah be upon him) said, “There are three people to whom Allah has forbidden Paradise: one who is addicted to wine, an undutiful son, and a cuckold who agrees to his womenfolk’s adultery.” (Tirmidhi, Ahmad and Nasa‘i)
Among the effects of zina are:
-It earns the wrath of Allaah.
-Darkening of the face, and darkness of the heart and the extinguishing of their light.
– Loss of respect towards the one who does it, and the lowering of his status in the eyes of his Lord and in the eyes of His slaves.
-Causes him to lose the title of believer, as the Prophet (peace and blessings of Allaah be upon him) said: “No adulterer is a believer at the moment when he is committing adultery.”
-Exposes one to the possibility of being one of the inhabitants of the oven (tannoor) in which the Prophet saw the adulterers and adulteresses.
– Causes one to lose the best of attributes and replaces it with the evil which Allaah described as the attribute of the adulterers.
-Vulnerable to different incurable diseases.
In summary, zina is a sin that is most likely to bring about evil in this world and the Hereafter, and the most likely to prevent good in this world and in the Hereafter.
