Surat Al Anfal: (39-40)

{وَقَاتِلُوهُمْ حَتَّى لاَ تَكُونَ فِتْنَةٌ وَيَكُونَ الدِّينُ كُلُّهُ لِلّه فَإِنِ انتَهَوْاْ فَإِنَّ اللّهَ بِمَا يَعْمَلُونَ بَصِيرٌ} [الأنفال: 39]

39- O Muslims, fight the disbelievers so that disbelief would cease, Muslims would not divert away from their religion, and religion shall be solely for Allah. However, if they cease, stop fighting them because Allah is well-acquainted with their belief and their returning to the truth, and shall forgive and reward them the best.

{وَإِن تَوَلَّوْاْ فَاعْلَمُواْ أَنَّ اللّهَ مَوْلاَكُمْ نِعْمَ الْمَوْلَى وَنِعْمَ النَّصِيرُ} [الأنفال: 40]

40- Nevertheless, if they insist on disbelief and polytheism, let it be known, O Muslims, that Allah will provide you victory, manage your affairs, and help you over them. So, put your trust in Allah, and do not pay attention to their enmity to you, for He is the best guardian who does not neglect His Subjects, and the best helper who pushes away the evil of enemies.
