What is "quzah"

Quzah is a Pre-Islamic Arabic god of weather, worshiped by the people of Muzdalifah. The pre-Islamic rite of the Ifada celebrated after the autumnal equinox was performed facing the direction of Quzah's sanctuary. A lasting reference to Quzah, is the Arabic qaws Quzah, "Bow of the God Quzah", which became the Arabic term for rainbow.
