Say, "O you who are Jews, if you claim that you are allies of Allah, excluding the [other] people, then wish for death, if you should be truthful."

Say: "O ye that stand on Judaism! If ye think that ye are friends to Allah, to the exclusion of (other) men, then express your desire for Death, if ye are truthful!"

But they will never wish for that because of what their hands have done.1 (62: 6-7)

— English Translation (Yusuf Ali)

i.e., disobeying Allah, killing some of the prophets (including Zachariah and John the Baptist), claiming to have killed Jesus, accusing Mary of adultery, and dealing with usury. See 4:153-158.
