I recently heard that the term 'Sayed' is not limited to the children of the holy prophet (s), but to anyone who is belongs to bani Hashem. This argument didn't make sense to me, because then that would mean that Abu Lahab (l.a.) would also be considered a Sayed... Could anyone clarify where the term came from, where and when it was first used and who it refers to? Thank you in advance. Wslm
