Is it permissible to marry the daughters of paternal uncles and aunts whom the grandfather's wife did not nurse, knowing that the grandfather's wife nursed the questioner?

If you were nursed by a woman with five full breastfeeds resulting from your grandfather's cohabitation with her, then you are a brother to your father, paternal uncles, and paternal aunts through rada'a (milk-kinship). The children of your paternal uncles and paternal aunts are therefore the children of your brothers and sisters through rada'a. Based on this, it is unlawful for you to marry any of their females, as the Prophet, peace and blessings be upon him, said: "What is unlawful by lineage is unlawful by rada'a (milk-kinship)."
