Is it permissible for me to marry the daughters of my paternal uncle's other wife, if one of his wives breastfed me?

If your uncle's wife breastfed you five times within two years, she becomes your mother, and your uncle becomes your father. All of their children, male and female, become your siblings through suckling. If the girls in question are your uncle's daughters, they are forbidden to you. However, if they are from another husband who is not your uncle, then there is no objection to you marrying them. Sheikh Ibn Baz clarified that the suckling child becomes the child of the wet nurse and her husband, who is the owner of the milk, and all of the couple's children become siblings to the suckling child.
