And the zina of an old man who is of sound mind is worse than the zina of a young man, and the zina of a free man or a knowledgeable man is worse than the zina of a slave or one who is ignorant. The expiation for committing zina with a married woman or any other is sincere repentance that fulfils all the conditions of repentance.
That involves giving up the sin completely, regretting what one has done and resolving never to go back to it.
Allah says: “The adulterer cannot marry any but an adulteress or an idolatress, and the adulteress, none mary her but an adulterer or an idolater; to the believers such a thing is forbidden” [: 3] Please note that extra-marital affairs may not involve any sex.
It could be an emotional affair via the internet, and that may itself be equally problematic and dangerous.
[…] Secondly: If marriage takes place after a haram relationship between a man and woman, then one of the following scenarios must apply: 1.
Either that marriage comes after an illegitimate sexual relationship, in which case the marriage is not valid except on the condition that both the man and woman repent from zina and it be established that the woman is not pregnant as a result of the haram relationship, because Allah, may He be exalted, says (interpretation of the meaning): âThe adulterer/fornicator marries not but an adulteress/fornicatress or a Mushrikah; and the adulteress/fornicatress, none marries her except an adulterer/fornicater or a Mushrik and that means that the man who agrees to marry (have a sexual relation with) a Mushrikah (female polytheist, pagan or idolatress) or a prostitute, then surely, he is either an adulterer/fornicator, or a Mushrik (polytheist, pagan or idolater).
In The Qur’an in (Surah 17, al Isra,, verse 32), Allah says:” [Sahîh al-Bukhârî and Sahîh Muslim] A young man once came to our Prophet (peace be upon him) and said: “O, Messenger of Allah give me a permission to commit fornication.” The Companions were angry with the way that young man who dared to ask such a thing from the Prophet (peace be upon him), but the Prophet (peace be upon him) did not grow angry and immediately asked him: “Would you like a man to fornicate with your mother?
If it is done with a non-mahram woman who has no husband it is a serious matter.Whoever does that has repented to Allaah, and whoever repents, Allaah will accept his repentance and turn his bad deeds into good deeds, as Allaah says (interpretation of the meaning): Know they not that Allaah accepts repentance from His slaves and takes the Sadaqaat (alms, charity), and that Allaah Alone is the One Who forgives and accepts repentance, Most Merciful?
