All the relations which become haram on account of lineage also become haram on account of breast-feeding. In other words, if a girl is breast-fed by a particular woman, then this girl cannot marry the latter’s husband because he will now be regarded as her father.

All the maternal and paternal uncles and maternal and paternal nephews who become related due to this breast-feeding also become haram on this girl.
If two girls have been breast-fed by one woman, they cannot marry the same man at one time. In other words, whatever has been explained previously, will also apply to relations based on breast-feeding.
