Avoidance of envy and injustice

وَلَا تَتَمَنَّوْا۟ مَا فَضَّلَ ٱللَّهُ بِهِۦ بَعْضَكُمْ عَلَىٰ بَعْضٍۢ ۚ لِّلرِّجَالِ نَصِيبٌۭ مِّمَّا ٱكْتَسَبُوا۟ ۖ وَلِلنِّسَآءِ نَصِيبٌۭ مِّمَّا ٱكْتَسَبْنَ ۚ وَسْـَٔلُوا۟ ٱللَّهَ مِن فَضْلِهِۦٓ ۗ إِنَّ ٱللَّهَ كَانَ بِكُلِّ شَىْءٍ عَلِيمًۭا

And in no wise covet those things in which Allah Hath bestowed His gifts More freely on some of you than on others: To men is allotted what they earn, and to women what they earn: But ask Allah of His bounty. For Allah hath full knowledge of all things.
