Repenting of Zina and then going back to it

A: Whoever fornicates and then repents, but falters and sins again, and later feels no inclination to repeat this sin after having got married, his repentance will be accepted when he fulfills the conditions of repentance. It is Allah's right that three conditions be fulfilled: admitting the sin one committed, feeling regret for what one did as a form of glorifying Allah and worshiping Him sincerely, and finally resolving not to repeat the sin again. On the other hand, conditions of repentance are four as regards people's rights: the three conditions mentioned above and the fourth is giving back the rights of people if possible and asking their forgiveness and pardon. We remind you of Allah's Statement: O you who believe! Turn to Allâh with sincere repentance! This Ayah is from Surah Al-Tahrim. Allah (Exalted be He) also states: (Part No. 24; Page No. 341) ...they invoke not any other ilâh (god) along with Allâh, nor kill such person as Allâh has forbidden, except for just cause, nor commit illegal sexual intercourse - and whoever does this shall receive the punishment. The torment will be doubled to him on the Day of Resurrection, and he will abide therein in disgrace; Except those who repent and believe (in Islâmic Monotheism), and do righteous deeds; for those, Allâh will change their sins into good deeds, and Allâh is Oft-Forgiving, Most Merciful. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
