Q: A person requests a Fatwa for the following question:
I concluded marriage with my wife in 22/3/1411 A.H. then I had sexual intercourse with her. Afterwards she became pregnant and gave birth to a male baby in good health in 23/9/1411 A.H. People raised doubts because of the short period of pregnancy.
I would like to receive your Fatwa with regard to the relation of this baby to me. I do not doubt my wife. She was married to another man before me and she was divorced from her ex-husband without having children. She stayed at her father's house for three years until I proposed to her, concluded marriage, and had sexual intercourse with her. I appreciate your advice. May Allah grant you success!
If the reality is as you have mentioned, the boy is your son because it came after the least period of pregnancy between consummation and delivery. Allah (Exalted be He) says,
...and the bearing of him, and the weaning of him is thirty months
The mothers shall give suck to their children for two whole years
The period of suckling is two years i.e. 24 months out of 30 months and the remaining 6 months is the least period of pregnancy. Subsequently, the woman's pregnancy is legal and the boy is legally ascribed to you. (Part No. 20; Page No. 337) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
