Qur'an 6:65

قُلْ هُوَ ٱلْقَادِرُ عَلَىٰٓ أَن يَبْعَثَ عَلَيْكُمْ عَذَابًا مِّن فَوْقِكُمْ أَوْ مِن تَحْتِ أَرْجُلِكُمْ أَوْ يَلْبِسَكُمْ شِيَعًا وَيُذِيقَ بَعْضَكُم بَأْسَ بَعْضٍ ۗ ٱنظُرْ كَيْفَ نُصَرِّفُ ٱلْـَٔايَـٰتِ لَعَلَّهُمْ يَفْقَهُونَ

“Say, "He is the [one] Able to send upon you affliction from above you or from beneath your feet or to confuse you [so you become] sects and make you taste the violence of one another." Look how We diversify the signs that they might understand.”
