Surah Al-An'aam, Verse 65
قُلْ هُوَ ٱلْقَادِرُ عَلَىٰٓ أَن يَبْعَثَ عَلَيْكُمْ عَذَابًۭا مِّن فَوْقِكُمْ أَوْ مِن تَحْتِ أَرْجُلِكُمْ أَوْ يَلْبِسَكُمْ شِيَعًۭا وَيُذِيقَ بَعْضَكُم بَأْسَ بَعْضٍ ۗ ٱنظُرْ كَيْفَ نُصَرِّفُ ٱلْءَايَٰتِ لَعَلَّهُمْ يَفْقَهُونَ
Translation — Sahih International
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.
