1) Sabeen as a Rroughly homophonic to an Arabic noun: "Sabi-een". 2) Sabi-een is a plural form of Sabi' means: Rebel (Peacfully). And the Suffix "een" is to make (Masculine) nouns in a plural form. 3) Sabi' was not a name but A nickname and It faded away ever since conquest of Mecca by the Prophet Muhammad. 4) I Never Heard any one named or called "Sabeen", so I think that this "Sabeen (as a name)" is something of no existence in Arabic or among Arabs. not to mention its disapproving meaning.
