قُلۡ هُوَ ٱلرَّحۡمَٰنُ ءَامَنَّا بِهِۦ وَعَلَيۡهِ تَوَكَّلۡنَاۖ فَسَتَعۡلَمُونَ مَنۡ هُوَ فِي ضَلَٰلٖ مُّبِينٖ
Say, "He is The All-Merciful. We believe in Him, and in Him we put our trust. So, you will soon know who it is that is in evident error"
قُلۡ أَرَءَيۡتُمۡ إِنۡ أَصۡبَحَ مَآؤُكُمۡ غَوۡرٗا فَمَن يَأۡتِيكُم بِمَآءٖ مَّعِينِۭ
Say, "Have you seen (that) in case your water becomes in the morning deep-sunken, (i.e., in the earth) then who would come up to you with (i.e., bring) profuse water?"
