قُلْ أَرَءَيْتُمْ إِن جَعَلَ ٱللَّهُ عَلَيْكُمُ ٱلنَّهَارَ سَرْمَدًا إِلَىٰ يَوْمِ ٱلْقِيَـٰمَةِ مَنْ إِلَـٰهٌ غَيْرُ ٱللَّهِ يَأْتِيكُم بِلَيْلٍ تَسْكُنُونَ فِيهِ ۖ أَفَلَا تُبْصِرُونَ

Qul araaytum in jaAAala AllahuAAalaykumu annahara sarmadan ila yawmialqiyamati man ilahun ghayru Allahiya/teekum bilaylin taskunoona feehi afala tubsiroon
