﴿ إِلَّا مَن رَّحِمَ ٱللَّهُ ۚ إِنَّهُۥ هُوَ ٱلْعَزِيزُ ٱلرَّحِيمُ ﴾

“save those upon whom God will have bestowed His grace and mercy: for, verily, He alone is almighty, a dispenser of grace.”

except for him on whom God has mercy — and these are the believers for they will intercede for one another with God’s permission. He is indeed the Mighty the Victor in His retribution of the disbelievers the Merciful to believers.
