قُل أَرَأَيتُم إِن جَعَلَ اللَّهُ عَلَيكُمُ النَّهارَ سَرمَدًا إِلىٰ يَومِ القِيامَةِ مَن إِلـٰهٌ غَيرُ اللَّهِ يَأتيكُم بِلَيلٍ تَسكُنونَ فيهِ ۖ أَفَلا تُبصِرونَ

Say, "Have you considered: if Allah should make for you the day continuous until the Day of Resurrection, what deity other than Allah could bring you a night in which you may rest? Then will you not see?"
