The Rabaa or Rabbi'ah sign (, pronounced: ; ) - often stylized as R4BIA or less commonly as Rab3a, is a hand gesture and a sign that first appeared in late August 2013, thought to have originated from Turkey and used in social media and protest marches in Egypt. It is used by the Muslim Brotherhood and its supporters in Egypt in the wake of the overthrow of Mohamed Morsi, which occurred after anti-government protests calling for his removal. On July 9, 2014, a Brotherhood-affiliated organization declared August 14, the day when the sit-ins were dispersed, "World Rabia Day," in an attempt to garner support across numerous countries.
