وَٱللَّهُ ٱلَّذِىٓ أَرْسَلَ ٱلرِّيَٰحَ فَتُثِيرُ سَحَابًۭا فَسُقْنَٰهُ إِلَىٰ بَلَدٍۢ مَّيِّتٍۢ فَأَحْيَيْنَا بِهِ ٱلْأَرْضَ بَعْدَ مَوْتِهَا ۚ كَذَٰلِكَ ٱلنُّشُورُ
And Allah it is Who sendeth the winds and they raise a cloud; then We lead it unto a dead land and revive therewith the earth after its death. Such is the Resurrection.
