Bablefish translates the signs the women are holding as follows:
OUBLIER MOHAMMED – FORGET MOHAMMED
`A L’ENFER AVEC L’ISLAM – TO HELL WITH ISLAM
JE AI FINI AVEC L’ISLAM – I’VE ENDED UP WITH ISLAM
Though my decades old high school French makes me question if the last one shouldn’t be interpreted more like “I AM FINISHED/DONE WITH ISLAM.”
