﴿ وَلَوْ يُؤَاخِذُ ٱللَّهُ ٱلنَّاسَ بِمَا كَسَبُوا۟ مَا تَرَكَ عَلَىٰ ظَهْرِهَا مِن دَآبَّةٍۢ وَلَٰكِن يُؤَخِّرُهُمْ إِلَىٰٓ أَجَلٍۢ مُّسَمًّۭى ۖ فَإِذَا جَآءَ أَجَلُهُمْ فَإِنَّ ٱللَّهَ كَانَ بِعِبَادِهِۦ بَصِيرًۢا ﴾

“Now if God were to take men [at once] to task for whatever [wrong] they commit [on earth], He would not leave a single living creature upon its surface. However, He grants them respite for a term set [by Him]: but when their term comes to an end - then, verily, [they come to know that] God sees all that is in [the hearts of] His servants.”

Were God to take mankind to task for what they have acquired of acts of disobedience He would not leave on its surface that is the earth’s a single creature a single living thing moving thereon. But He reprieves them to an appointed term namely to the Day of Resurrection. And when their term comes — then truly they will know that God is ever Seer of His servants and so He will requite them according to the nature of their deeds rewarding the believers and punishing the disbelievers.
