Al-Anfal 8:39

Waqatiloohum hatta latakoona fitnatun wayakoona addeenu kulluhu lillahifa-ini intahaw fa-inna Allaha bima yaAAmaloona baseer

And fight against them until there is no fitnah and [until] the religion [i.e., worship], all of it, is for Allāh. And if they cease - then indeed, Allāh is Seeing of what they do.

And fight them until there is no Fitnah (mischief), and total obedience becomes for Allah. So, if they desist, then, Allah is indeed watchful over what they do.
