Does a husband become a father to a suckled infant through his wife suckling her, thus making her unlawful for him upon reaching puberty?
If you breastfeed the girl, you become her foster mother, and your husband becomes her foster father. It is stated in "Al-Mudawwana" that the milk belongs to the male even if the woman does not become pregnant, because intercourse stimulates milk production. The majority of scholars, however, are of the view that a prior pregnancy is not a condition for the establishment of prohibition through a woman's milk. Thus, the milk of a virgin who has not been intercoursed and has not conceived establishes prohibition, due to the generality of Allah's saying: "{and your mothers who breastfed you}," and because it is a woman's milk to which prohibition is attached.
