Q 1: I want to marry my maternal uncle's daughter, but her mother claims that (Part No. 21; Page No. 142) her daughter was
breastfed by my stepmother with one of my brothers. No one could identify how many times this happened,
because my stepmother died and the girl's mother was sick at the time of breastfeeding. However, the girl says that my stepmother used to say to her, "Why do not you obey me? I breast-fed you until you were satiated."This is the only evidence we have. Please advise. May Allah reward you! Is it lawful for me to marry this girl or not?
If the reality is as you mentioned, that breastfeeding really took place, but there was no way to confirm the number of times of breastfeeding because the breastfeeding woman had already died, and since she used before her death to ask the girl you want to marry to obey her, because she had breast-fed her until she was satiated, you would better not marry that girl, as she might have been breast-fed by your stepmother five times or more. It was authentically reported that the Prophet (peace be upon him) said:
"Leave what causes you doubt and turn to what does not cause you doubt."
You should also take into account the disagreement among the scholars in the times of breastfeeding that prohibit marriage.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
