@Diaa - FYI. / Bedouin - are an Arab seminomadic group, descended from nomads who have historically inhabited the Arabian and Syrian Deserts. Their name means "desert dwellers" in Arabic.
ARAB - Before the spread of Islam, Arab referred to any of the largely nomadic Semitic tribes inhabiting the Arabian Peninsula.
I have never seen any "ARABS" in TROPICAL countries or countries which Snows.
