What is the kinship relationship between Subay'ah al-Aslamiyyah and Abu al-Sanabil?

Question : O my brothers. And upon his family and all his Companions. How much? Thank you, young men. As for my time, only eight minutes remain. May Allah reward you, Honorable Shaykh. The questioner asks: What is the kinship relationship between Subay'ah al-Aslamiyyah and Abu al-Sanabil ibn Ba'akk? And is he a mahram (a relative one may not marry) to her?

Answer : I do not know. I do not know what is true. He may be a mahram through breastfeeding, in-law relations, or something else. I do not know about him. Yes.
