Does the milk kinship of a nursing mother and milk siblings lapse because of a difference in religion?

Summary

A difference in religion does not prevent breastfeeding or the formation of milk kinship, because the evidence on breastfeeding is general and does not mention religion. Mahram ties are established between a child and a nursing mother of another religion, and between milk siblings of different religions. A Muslim woman may not travel or be alone with a non-Muslim milk mahram whose character is corrupt or whose religion permits relations with mahrams. If the non-Muslim mahram is trustworthy, the majority of Hanafi, Maliki and Shafii scholars allow it, while the Hanbali school does not regard a non-Muslim as a mahram.
