An-Nahl - 16:71

وَاللّهُ فَضَّلَ بَعْضَكُمْ عَلَى بَعْضٍ فِي الْرِّزْقِ فَمَا الَّذِينَ فُضِّلُواْ بِرَآدِّي رِزْقِهِمْ عَلَى مَا مَلَكَتْ أَيْمَانُهُمْ فَهُمْ فِيهِ سَوَاء أَفَبِنِعْمَةِ اللّهِ يَجْحَدُونَ
[16:71]
And Allah has made some of you excel others in the means of subsistence, so those who are made to excel do not give away their sustenance to those whom their right hands possess so that they should be equal therein; is it then the favor of Allah which they deny?
Allah has bestowed His gifts of sustenance more freely on some of you than on others: those more favoured are not going to throw back their gifts to those whom their right hands possess, so as to be equal in that respect. Will they then deny the favours of Allah?
And Allah hath favoured some of you above others in provision. Now those who are more favoured will by no means hand over their provision to those (slaves) whom their right hands possess, so that they may be equal with them in respect thereof. Is it then the grace of Allah that they deny?
