The ruling on a married person

Q 5: What is the Islamic ruling on someone who committed Zina (sexual intercourse outside marriage) but no Had (ordained punishment for violating Allah’s Law) was inflicted on them? Bear in mind that they regretted what they had done and made Tawbah (repentance to Allah). Do they have to make Kaffarah (expiation)?

A: Anyone who commits a prohibited act then abstains from it, feels remorse, holds no intention of ever committing it again and makes sincere Tawbah, Allah (Glorified be He) will accept their repentance. Moreover, this person should mention Allah often and do as much righteous deeds as they can. Allah (Exalted be He) says: And verily, I am indeed forgiving to him who repents, believes (in My Oneness, and associates none in worship with Me) and does righteous good deeds, and then remains constant in doing them, (till his death). May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
