Quran 8:39 from Surah Al-Anfaal on Divine Marvels.
وَقَٰتِلُوهُمۡ حَتَّىٰ لَا تَكُونَ فِتۡنَةٞ وَيَكُونَ ٱلدِّينُ كُلُّهُۥ لِلَّهِۚ فَإِنِ ٱنتَهَوۡاْ فَإِنَّ ٱللَّهَ بِمَا يَعۡمَلُونَ بَصِيرٞ
English translation: And fight them until not there is oppression and is the religion all of it for Allah But if they ceased then indeed Allah of what they do (is) All-Seer
Transliteration: waqatiluhum hatta la takuna fit'natun wayakuna al-dinu kulluhu lillahi fa-ini intahaw fa-inna al-laha bima ya'maluna basirun
