Of course. How could anything from the Qur’an be hateful or inciting?
The billboards quote this Qur’an passage: “O you who have believed, do not take the Jews and the Christians as friends or allies. They are friends and allies of one another. And whoever is an ally to them among you – then indeed, he is of them. Indeed, Allah guides not the wrongdoing people.” (5:51)
What could be more peaceful?
