Q: I am engaged to the daughter of the sister of my father. In my child hood, mother of my father used to put her breast nipple in my mouth, whenever I cried. She was old then and had no milk in her breast. What I want to ask is it halal to marry with my cousin now?

Q: A child drank milk from a woman. Later vomited it all out. Would it be haram for this boy to marry this womans daughter. The families are very close to each other. (I said no, but they said, the boy vomit it out. i said, there is a possibility that some stayed in the stomach.) They want a response from a mufti saheb. To complicate it shiek Usaymeen of saudi arabia in his fatwa kitab said so long as it is not beyond 5 sucklings it is ok, this maybe the hanabila view. The person asking is hanafee)
