Quran 6:65

قُلۡ هُوَ ٱلۡقَادِرُ عَلَىٰٓ أَن يَبۡعَثَ عَلَيۡكُمۡ عَذَابً۬ا مِّن فَوۡقِكُمۡ أَوۡ مِن تَحۡتِ أَرۡجُلِكُمۡ أَوۡ يَلۡبِسَكُمۡ شِيَعً۬ا وَيُذِيقَ بَعۡضَكُم بَأۡسَ بَعۡضٍ‌ۗ ٱنظُرۡ كَيۡفَ نُصَرِّفُ ٱلۡأَيَـٰتِ لَعَلَّهُمۡ يَفۡقَهُونَ ٦٥

Say, "He is certainly able to pour upon you retribution from above you, or from beneath your feet. Or He can divide you into factions and have you taste each others’ tyranny. Note how we explain the revelations, that they may understand."
