Egyptian authorities have criminalised the four-fingered Rabaa sign used by supporters of the now-banned Muslim Brotherhood.
Egyptian council of ministers made the possession and distribution of "terrorism or hate-related articles, symbols and propaganda" illegal earlier this week.
The Muslim Brotherhood has been designated a terrorist organisation in Egypt, following the military coup against Islamist president Mohammad Morsi in 2013.
"The law bans carrying, printing, publishing and using signs and symbols of the Rabaa sit-in, the Muslim Brotherhood, the Islamic Group, the Anti-Coup Alliance, Ansar Bait al-Maqdis and the Islamic state group [IS]," an official told The New Arab.
The law punishes violators with up to five years in prison and fines of up to $3,800 if convicted.
The move comes days before the anniversary of the January 25 uprising, which ousted former president Hosni Mubarak.
The Rabaa sign is often used in anti-government protests and has come to symbolise Islamist opposition to the military government.
