4:2
وَءَاتُوا۟ ٱلْيَتَـٰمَىٰٓ أَمْوَٰلَهُمْ ۖ وَلَا تَتَبَدَّلُوا۟ ٱلْخَبِيثَ بِٱلطَّيِّبِ ۖ وَلَا تَأْكُلُوٓا۟ أَمْوَٰلَهُمْ إِلَىٰٓ أَمْوَٰلِكُمْ ۚ إِنَّهُۥ كَانَ حُوبًا كَبِيرًا
waātū l-yatāmā amwālahum walā tatabaddalū l-khabītha bil-ṭayibi walā takulū amwālahum ilā amwālikum innahu kāna ḥūban kabīran
Give orphans their property, do not replace [their] good things with bad, and do not consume their property with your own- a great sin.
And give unto orphans their property and do not exchange (your) bad things for (their) good ones; and devour not their substance (by adding it) to your substance. Surely, this is a great sin.
