And give to the orphans their properties and do not substitute the defective [of your own] for the good [of theirs]. And do not consume their properties into your own. Indeed, that is ever a great sin.
The Saheeh International Quran Translation
وَءَاتُوا۟ ٱلْيَتَٰمَىٰٓ أَمْوَٰلَهُمْ وَلَا تَتَبَدَّلُوا۟ ٱلْخَبِيثَ بِٱلطَّيِّبِ وَلَا تَأْكُلُوٓا۟ أَمْوَٰلَهُمْ إِلَىٰٓ أَمْوَٰلِكُمْ إِنَّهُۥ كَانَ حُوبًا كَبِيرًاAnd give to the orphans their properties and do not substitute the defective [of your own] for the good [of theirs]. And do not consume their properties into your own. Indeed, that is ever a great sin.
