{وَآتُوا الْيَتَامَىٰ أَمْوَالَهُمْ ۖ وَلَا تَتَبَدَّلُوا الْخَبِيثَ بِالطَّيِّبِ ۖ وَلَا تَأْكُلُوا أَمْوَالَهُمْ إِلَىٰ أَمْوَالِكُمْ ۚ إِنَّهُ كَانَ حُوبًا كَبِيرًا} [النساء : 2]


My translation:

And give the rich their food, and do not substitute the haram (fresh) of it, for what is left of the halal (ripened) of it, and don't hurt them in their confidence by underestimating it (food), for sure He is Willingly Robust. [4:2]
