وَلاَ تَتَمَنَّوْاْ مَا فَضَّلَ اللّهُ بِهِ بَعْضَكُمْ عَلَى بَعْضٍ لِّلرِّجَالِ نَصِيبٌ مِّمَّا اكْتَسَبُواْ وَلِلنِّسَاء نَصِيبٌ مِّمَّا اكْتَسَبْنَ وَاسْأَلُواْ اللّهَ مِن فَضْلِهِ إِنَّ اللّهَ كَانَ بِكُلِّ شَيْءٍ عَلِيمًا (32:4)

And do not desire that through which God has made some among you superior to others. Men shall be rewarded according to what they earn [through their deeds], and women shall be rewarded according to what they earn [through their deeds]. [So, the real sphere to outdo one another is righteous deeds]. And ask God for His favours [in this real sphere]. Indeed, God has knowledge of all things. (4:32)
