This passionate prayer for peace is attributed to a Palestinian source in several Global Song collections.
While the pronunciation of Arabic can differ from country to country, here is a recording of the text in the original language to guide you.
Yarabba ssalami amter alayna ssalam,
Yarabba ssalami im la’ qulubana ssalam.
God of Peace, rain peace upon us,
fill our hearts with peace.
God of peace and of justice, rain down upon us your peace.
God of peace and of justice, fill every heart with your peace.
