4:2

An-Nisaa 4:2

وَءَاتُوا۟ ٱلْيَتَٰمَىٰٓ أَمْوَٰلَهُمْ ۖ وَلَا تَتَبَدَّلُوا۟ ٱلْخَبِيثَ بِٱلطَّيِّبِ ۖ وَلَا تَأْكُلُوٓا۟ أَمْوَٰلَهُمْ إِلَىٰٓ أَمْوَٰلِكُمْ ۚ إِنَّهُۥ كَانَ حُوبًۭا كَبِيرًۭا

Wa aatul yataamaaa amwaalahum wa laa tatabad dalul khabeesa bittaiyibi wa laa taakulooo amwaalahum ilaaa amwaalikum; innahoo kaana hooban kabeeraa

Give orphans their property, and do not exchange the bad for the good, and do not eat up their property by mixing it with your own. This surely is a mighty sin.
