Is it permissible to marry the sister of the husband of the sister whom the sister breastfed for six months?

If your sister breastfed a girl five times within two years, that girl becomes her daughter through suckling, and it is forbidden for you to marry her, as the Prophet, peace and blessings be upon him, said: "What is unlawful by lineage is unlawful by suckling."
