﴿ فَٱنظُرْ إِلَىٰٓ ءَاثَٰرِ رَحْمَتِ ٱللَّهِ كَيْفَ يُحْىِ ٱلْأَرْضَ بَعْدَ مَوْتِهَآ ۚ إِنَّ ذَٰلِكَ لَمُحْىِ ٱلْمَوْتَىٰ ۖ وَهُوَ عَلَىٰ كُلِّ شَىْءٍۢ قَدِيرٌۭ ﴾

“Behold, then, [O man,] these signs of God’s grace - how He gives life to the earth after it had been lifeless! Verily, this Selfsame [God] is indeed the One that can bring the dead back to life: for He has the power to will anything!”

So behold the effects a variant reading has singular athar ‘the effect’ of God's mercy that is His grace in giving them rain how He revives the earth after it has died after it has dried out so that it produces vegetation again. Surely He is the Reviver of the dead and He has power over all things.
