AL ANFAAL — Ayat 39

وَقَاتِلُوهُمْ حَتَّى لاَ تَكُونَ فِتْنَةٌ وَيَكُونَ الدِّينُ كُلُّهُ لِلّه فَإِنِ انتَهَوْاْ فَإِنَّ اللّهَ بِمَا يَعْمَلُونَ بَصِيرٌ

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