وَٱبْتَلُوا۟ ٱلْيَتَٰمَىٰ حَتَّىٰٓ إِذَا بَلَغُوا۟ ٱلنِّكَاحَ فَإِنْ ءَانَسْتُم مِّنْهُمْ رُشْدًۭا فَٱدْفَعُوٓا۟ إِلَيْهِمْ أَمْوَٰلَهُمْ ۖ وَلَا تَأْكُلُوهَآ إِسْرَافًۭا وَبِدَارًا أَن يَكْبَرُوا۟ ۚ وَمَن كَانَ غَنِيًّۭا فَلْيَسْتَعْفِفْ ۖ وَمَن كَانَ فَقِيرًۭا فَلْيَأْكُلْ بِٱلْمَعْرُوفِ ۚ فَإِذَا دَفَعْتُمْ إِلَيْهِمْ أَمْوَٰلَهُمْ فَأَشْهِدُوا۟ عَلَيْهِمْ ۚ وَكَفَىٰ بِٱللَّهِ حَسِيبًۭا
Prove orphans till they reach the marriageable age; then, if ye find them of sound judgment, deliver over unto them their fortune; and devour it not by squandering and in haste lest they should grow up Whoso (of the guardians) is rich, let him abstain generously (from taking of the property of orphans); and whoso is poor let him take thereof in reason (for his guardianship). And when ye deliver up their fortune unto orphans, have (the transaction) witnessed in their presence. Allah sufficeth as a Reckoner.
