2وَآتُوا اليَتامىٰ أَموالَهُم ۖ وَلا تَتَبَدَّلُوا الخَبيثَ بِالطَّيِّبِ ۖ وَلا تَأكُلوا أَموالَهُم إِلىٰ أَموالِكُم ۚ إِنَّهُ كانَ حوبًا كَبيرًا(Irfan-ul-Quran)And deliver to the orphans their belongings; and do not exchange the bad for the good; nor consume their wealth by mixing it with your own. Indeed this is a great sin.
