Sayyid (Arabic: سیّد, feminine: Sayyida(سیّدة), Arabic plural: Sada (سادة); noun: Siyada (سیادة)) is an Arabic honorific title denoting descendants of prophet Muhammad (s). According to fiqh, it is a title given to the descendants of Hashim b. Abd Manaf (the Prophet's great grandfather).
@shortstories The word in the poster (Saad) is just an Arabic name it has nothing to do with the word (سيد sayyid ) Arabic is confusing I am sorry for that
