وَٱللَّهُ فَضَّلَ بَعْضَكُمْ عَلَىٰ بَعْضٍۢ فِى ٱلرِّزْقِ ۚ فَمَا ٱلَّذِينَ فُضِّلُوا۟ بِرَآدِّى رِزْقِهِمْ عَلَىٰ مَا مَلَكَتْ أَيْمَٰنُهُمْ فَهُمْ فِيهِ سَوَآءٌ ۚ أَفَبِنِعْمَةِ ٱللَّهِ يَجْحَدُونَ
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?
