Disbelievers are protectors amongst themselves

وَٱلَّذِينَ كَفَرُوا۟ بَعْضُهُمْ أَوْلِيَآءُ بَعْضٍ ۚ إِلَّا تَفْعَلُوهُ تَكُن فِتْنَةٌۭ فِى ٱلْأَرْضِ وَفَسَادٌۭ كَبِيرٌۭ

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.
