4:6
وَ ٱبْتَلُ وا۟ ٱلْ يَتَٰمَىٰ حَتَّىٰٓ إِذَا بَلَغُ وا۟ ٱل نِّكَاحَ فَ إِنْ ءَانَسْ تُم مِّنْ هُمْ رُشْدًا فَ ٱدْفَعُ وٓا۟ إِلَيْ هِمْ أَمْوَٰلَ هُمْ وَ لَا تَأْكُلُ و هَآ إِسْرَافًا وَ بِدَارًا أَن يَكْبَرُ وا۟ وَ مَن كَانَ غَنِيًّا فَ لْ يَسْتَعْفِفْ وَ مَن كَانَ فَقِيرًا فَ لْ يَأْكُلْ بِ ٱلْ مَعْرُوفِ فَ إِذَا دَفَعْ تُمْ إِلَيْ هِمْ أَمْوَٰلَ هُمْ فَ أَشْهِدُ وا۟ عَلَيْ هِمْ وَ كَفَىٰ بِ ٱللَّهِ حَسِيبًا
And test the orphans [in their abilities] until they reach marriageable age. Then if you perceive in them sound judgement, release their property to them. And do not consume it excessively and quickly, [anticipating] that they will grow up. And whoever, [when acting as guardian], is self-sufficient should refrain [from taking a fee]; and whoever is poor - let him take according to what is acceptable. Then when you release their property to them, bring witnesses upon them. And sufficient is Allah as Accountant.
