النساۤء — An-Nisa' Ayat 2
وَاٰتُوا الْيَتٰمٰىٓ اَمْوَالَهُمْ وَلَا تَتَبَدَّلُوا الْخَبِيْثَ بِالطَّيِّبِ ۖ وَلَا تَأْكُلُوْٓا اَمْوَالَهُمْ اِلٰٓى اَمْوَالِكُمْ ۗ اِنَّهٗ كَانَ حُوْبًا كَبِيْرًا
Wa ātul-yatāmā amwālahum wa lā tatabaddalul-khabīṡa biṭ-ṭayyib(i), wa lā ta'kulū amwālahum ilā amwālikum, innahū kāna ḥūban kabīrā(n).
"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."
