Surah Al-Anfal, Verse 73

وَٱلَّذِينَ كَفَرُواْ بَعۡضُهُمۡ أَوۡلِيَآءُ بَعۡضٍۚ إِلَّا تَفۡعَلُوهُ تَكُن فِتۡنَةࣱ فِي ٱلۡأَرۡضِ وَفَسَادࣱ كَبِيرࣱ‏ ﴿٧٣﴾

Vellezıne keferu ba´duhüm evliyaü ba´d illa tef´aluhü tekün fitnetün fel erdı ve fesadün kebır

“The Unbelievers are protectors, one of another: Unless ye do this, (protect each other), there would be tumult and oppression on earth, and great mischief”
