No doubt zina (adultery or fornication) is one of the gravest sins that incur Allah’s severest punishment on the Day of Judgment. Allah Almighty says, (And come not near unto adultery. Lo! it is an abomination and an evil way.) (Al-Israa’ 17: 32). The sin becomes heinous when it comes to committing incest. It is the most serious offense and enormity in the Sight of Allah, the Almighty.
Therefore, a true Muslim should steer clear of any temptations that might drag him into disobeying Allah. If one is, however, overwhelmed by Satanic temptations, then he should hasten to forward sincere repentance to Allah. After that he should strive hard to do as many righteous deeds as he can, recite the Glorious Qur’an over and again, attending religious lectures and keep accompanying those who will help him remember Allah and the Day of Judgment. Allah Almighty says: (And those who cry not unto any other god along with Allah, nor take the life which Allah hath forbidden save in (course of) justice, nor commit adultery and whoso doeth this shall pay the penalty. The doom will be doubled for him on the Day of Resurrection, and he will abide therein disdained for ever. Save him who repenteth and believeth and doth righteous work; as for such, Allah will change their evil deeds to good deeds. Allah is ever Forgiving, Merciful.) (Al-Furqan 25: 68-70)
To curb this heinous crime if it is rampant in a society, the basic procedures should start with Islamic education by warning against the enormity of this sin and its evil consequences in the Hereafter in addition to the negative social and psychological consequences. We should follow the Islamic teachings which require taking the necessary cautions in the relations between the opposite sexes even if they are mahram (unmarriageable relatives) as long as temptation is feared. For instance, Islam orders the parents to separate their children in beds when they reach the age of discretion. `Amr ibn Shu`ayb narrated from his father on the authority of his grandfather that the Prophet (peace and blessings be upon him) said: “Order your children to pray at the age of seven, hit them to do so at the age of ten, and separate them (the boys from the girls) in their beds.” (Reported by Ahmad, Abu Dawud and al-Hakim)
Moreover, it is the responsibility of the society to fight against all forms of moral corruption and indecency and ban all means that incite desires and call for immorality.
