1 verse has
obligation
in Edition Clear Qur'an by Talal Itani / Aal-i-Imraan (The Family of Imraan)

3:75Among the People of the Book is he, who, if you entrust him with a heap of gold, he will give it back to you. And among them is he, who, if you entrust him with a single coin, he will not give it back to you, unless you keep after him. That is because they say, “We are under no obligation towards the gentiles.” They tell lies about God, and they know it.
