Ibn Abbaas (RAA) said: There is no major sin if one asks for forgiveness, and there is no minor sin if one persists in repeating it.
So if one wants to repent from having made the great sin of Zina he should remember these 4 things..
1) Do not despair, for Allah the Most Exalted and Glorified said in the Quran "Say: Oh my servants who have transgressed against their souls! Despair not of the mercy of Allah, for Allah forgives all sins; for He is oft-forgiving, most merciful." [Surah 39, Verse 53]
2) Let your repentance be truly from your heart, and stay away from all sources of temptations. Also, perform many good deeds, as good deeds abrogate the bad ones.
3) If you repent to Allah, you are no longer described as a fornicator (zaani). Therefore, you can marry a chaste man or woman.
4) The believer has high hope and aspiration for the best from Allah. He not only asks Allah for making his punishment easy in hellfire, but he also prays to Allah the Almighty to save him from Hell and award him with paradise for his repentance and good deeds.
