When you are comparing your results to someone else's
What a person is credited with, stated plainly.
وَأَن لَّيْسَ لِلْإِنسَـٰنِ إِلَّا مَا سَعَىٰ وَأَنَّ سَعْيَهُۥ سَوْفَ يُرَىٰ ثُمَّ يُجْزَىٰهُ ٱلْجَزَآءَ ٱلْأَوْفَىٰ
Wa an laysa li-l-insāni illā mā saʿā, wa anna saʿyahu sawfa yurā, thumma yujzāhu-l-jazā'a-l-awfā.
“And that there is not for man except that [good] for which he strives And that his effort is going to be seen - Then he will be recompensed for it with the fullest recompense -”
