Are the sons and daughters of the nursing mother considered maternal uncles and aunts to the mother through rada'a (nursing), and is it permissible to marry their daughters?

If your mother nursed a woman, then that woman's sons become your maternal uncles (akhwal), and her daughters become your maternal aunts (khalat). It is permissible for you to marry the daughters of your maternal uncles and aunts through suckling, because they are not محرمات (unmarriageable) to you. It is a condition that the suckling consists of five satisfying feedings.
