Quran 33:61 — The Parties (Al-Ahzab)

They have incurred condemnation wherever they go; (unless they stop attacking you,) they may be taken and killed.

[33:60] Unless the hypocrites, and those with disease in their hearts, and the vicious liars of the city refrain (from persecuting you), we will surely grant you the upper hand, then they will be forced to leave within a short while.

[33:62] This is GOD's eternal system, and you will find that GOD's system is unchangeable.
