Is it permissible to marry the daughter of one's paternal aunt if that aunt is the foster mother to both the person himself and the paternal aunt's son?

By being nursed by your paternal aunt, she became your mother through suckling (رضاعة), and all her sons and daughters became your siblings. Therefore, it is unlawful for you to marry any of her daughters, based on the Almighty's saying: (and your sisters through suckling).
