Kur’an 4:6 — sura An-Nisa, 6. ajet

وَٱبۡتَلُواْ ٱلۡيَتَٰمَىٰ حَتَّىٰٓ إِذَا بَلَغُواْ ٱلنِّكَاحَ فَإِنۡ ءَانَسۡتُم مِّنۡهُمۡ رُشۡدٗا فَٱدۡفَعُوٓاْ إِلَيۡهِمۡ أَمۡوَٰلَهُمۡۖ وَلَا تَأۡكُلُوهَآ إِسۡرَافٗا وَبِدَارًا أَن يَكۡبَرُواْۚ وَمَن كَانَ غَنِيّٗا فَلۡيَسۡتَعۡفِفۡۖ وَمَن كَانَ فَقِيرٗا فَلۡيَأۡكُلۡ بِٱلۡمَعۡرُوفِۚ فَإِذَا دَفَعۡتُمۡ إِلَيۡهِمۡ أَمۡوَٰلَهُمۡ فَأَشۡهِدُواْ عَلَيۡهِمۡۚ وَكَفَىٰ بِٱللَّهِ حَسِيبٗا

I provjeravajte siročad dok ne stasaju za brak; pa ako ocijenite da su zreli, uručite im imetke njihove. I ne žurite da ih rasipnički potrošite dok oni ne odrastu. Ko je imućan – neka se uzdrži, a ko je siromašan – neka onoliko koliko mu je, prema običaju, neophodno troši. A imetke im uručujte u prisustvu svjedoka. A dosta je to što će se pred Allahom račun polagati.

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
