وَقَاتِلُوهُمْ حَتَّى لاَ تَكُونَ فِتْنَةٌ وَيَكُونَ الدِّينُ كُلُّهُ لِلّه فَإِنِ انتَهَوْاْ فَإِنَّ اللّهَ بِمَا يَعْمَلُونَ بَصِيرٌ
﴿٣٩﴾
سورة الأنفال
(8/39) And fight against them until there be no temptations and their obedience be wholly unto Allah. So if they desist, thens verily Allah is the Beholder of that which they do.
Surah Al-Anfal
