﴿ يَوْمَ تُوَلُّونَ مُدْبِرِينَ مَا لَكُم مِّنَ ٱللَّهِ مِنْ عَاصِمٍۢ ۗ وَمَن يُضْلِلِ ٱللَّهُ فَمَا لَهُۥ مِنْ هَادٍۢ ﴾

“the Day when you will [wish to] turn your backs and flee, having none to defend you against God: for he whom God lets go astray can never find any guide.”

Pharaoh had threatened Moses with worldly punishment. In reply to this, the True Believer warned Pharaoh of the punishment of the Hereafter. This is always the method of the preacher of Truth. People fret about worldly affairs, but the preacher is focused on the Hereafter. People talk in terms of the world, while the preacher’s discourse is always about the Hereafter. People consider worldly problems to be the most pressing, while, for the preacher, the most pressing problem is that which is connected with the Hereafter.
