Is Consentual Sex A Sin Against Human Or A Sin Against Allah?
God made extramarital sex a crime, not just sin, to save the family unit. It causes usurpation of rights if family. Since Gid has forbidden it, violating His command is a crime too. Therefore if one has beg for forgiveness from God and his family too and his child from the illicit relation.
Thank you for your response Dr. Irfan. Extramarital relationship in my opinion is also a crime against the person’s wife. But, my original question was assuming an unmarried person.
