May Allah bestow good upon you oh noble Shaykh. There's a man who committed illegal sexual intercourse with a woman and she became pregnant. Afterwards he married her. What is the ruling of this marriage?
If he married her during her pregnancy or before her repentance from the act of illegal sexual intercourse, the marriage is invalid and it's a must that they be separated until she has one menstrual cycle, becomes clean and she repents with a truthful repentance from the act of illegal sexual intercourse. After that it is permissible for the man to marry her by way of her guardian. As for the case of his marriage to her taking place after she gave birth and after she repented with a truthful repentance and he married her by way of her guardian and two witnesses, the marriage is valid.
