Zi'b
Zi'b was a Banu Sulaym Arab tribe whose grazing grounds lay between Mecca and Medina, around al-Suwariqiyya, al-Ghuraba and the Rabadha reserve. It traced its descent from Zi'b ibn Malik.
Around 1400 the Banu Lam, with whom Zi'b had dominated the high Najd, migrated north to Iraq and Syria. A later war with the Sharif of Mecca broke Zi'b: most moved east to the Gulf coast, while other clans took refuge in the Hauran, Jordan and Palestine, and their Hejazi wells passed to others.
