Is it permissible for me to marry a girl who was suckled with my brother?

If a person nurses from a woman, he becomes her son through suckling and a brother to all her children. So, if you nursed from the girl's mother, or she nursed from your mother, or you both nursed from the same woman, then she is your sister through suckling and it is forbidden to marry her. However, if there was no prohibitive suckling, then it is not forbidden for you to marry her. The prohibitive suckling, according to the preponderant opinion, consists of five satisfying sucklings.
