وَمِنْ ءَايَٰتِهِۦٓ أَنَّكَ تَرَى ٱلْأَرْضَ خَٰشِعَةًۭ فَإِذَآ أَنزَلْنَا عَلَيْهَا ٱلْمَآءَ ٱهْتَزَّتْ وَرَبَتْ ۚ إِنَّ ٱلَّذِىٓ أَحْيَاهَا لَمُحْىِ ٱلْمَوْتَىٰٓ ۚ إِنَّهُۥ عَلَىٰ كُلِّ شَىْءٍۢ قَدِيرٌ
And of His portents (is this): that thou seest the earth lowly, but when We send down water thereon it thrilleth and groweth. Lo! He Who quickeneth it is verily the Quickener of the Dead. Lo! He is Able to do all things.
