Bablefish translates the signs the women are holding as follows:
OUBLIER MOHAMMED FORGET MOHAMMED
`A LENFER AVEC LISLAM TO HELL WITH ISLAM
JE AI FINI AVEC LISLAM IVE 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.”
