Arabic text
وَٱلَّذِينَ كَفَرُواْ بَعۡضُهُمۡ أَوۡلِيَآءُ بَعۡضٍۚ إِلَّا تَفۡعَلُوهُ تَكُن فِتۡنَةٞ فِي ٱلۡأَرۡضِ وَفَسَادٞ كَبِيرٞ
And those who disbelieved are allies of one another. If you do not do so [i.e., ally yourselves with other believers], there will be fitnah [i.e., disbelief and oppression] on earth and great corruption.
