From Sahih Muslim (Hadith 5744):
Jabir reported that Umm Salama sought permission from Allah's messenger (may Allah's peace upon him) tor getting herself cupped. The Apostle of Allah (ﷺ) asked Abu Taiba to cup her. He (Jabir) said:I think he (Abu Taiba) was her faster brother or a young boy before entering upon the adolescent period
