Is it permissible for my sister's daughter to marry a man whose sister and I were nursed by his mother?

Nursing establishes the same prohibitions as lineage; thus, what is forbidden by lineage is also forbidden by nursing. The nursed child becomes a son to the woman and to the owner of the milk, but not to his siblings. Therefore, if the maternal uncle of a girl nurses alongside the sister of the suitor, this does not make that girl impermissible for her aforementioned suitor. The nursing here is specific to the uncle and does not include his sister's daughter. The nursing that establishes prohibition consists of five full, satisfying breastfeeds.
