Sahih Muslim | Book 26 | Hadith Number 5469
Narrated by Jabir
Jabir reported that Umm Salama sought permission from Allah's messenger (may Allah's peace upon him) for getting herself cupped. The Apostle of Allah (may peace be upon him) 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.
