A free Arabic typeface called Lifta, named after the Palestinian village destroyed in the 1948 occupation:
Lifta is a bold protest typeface available in black and stencil versions […] it is a typeface that protests the erasure of Palestinian identity and the subjugation of their rights as they live under occupation. It is designed by Omaima Dajani who is from East Jerusalem and living under occupation today. The design above is dedicated to Palestinian refugees around the world […]
If you’re looking to make any protest posters in Arabic, this could be a cost-effective typeface to use.
