Does breastfeeding while having no milk create a relationship of Mahram?

Q: A woman breastfed a boy with a girl only once. The boy did not suck milk. They grew and matured and now want to marry, but the two parties preferred waiting to hear your advice. May Allah preserve you!

A: If the case is as mentioned above and the wet-nurse did not pour milk into the mouth of the baby, there would be no blame on the boy to marry the girl as long as there is no other reason prohibiting the marriage except what was mentioned. (Part No. 21; Page No. 53) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
