وَلَا تَقۡرَبُواْ مَالَ ٱلۡيَتِيمِ إِلَّا بِٱلَّتِي هِيَ أَحۡسَنُ حَتَّىٰ يَبۡلُغَ أَشُدَّهُۥۚ وَأَوۡفُواْ بِٱلۡعَهۡدِۖ إِنَّ ٱلۡعَهۡدَ كَانَ مَسۡـُٔولٗا
Wa laa taqraboo maalal yateemi illaa billatee hiya ahsanu hattaa yablugha ashuddah; wa awfoo bil'ahd, innal 'ahda kaana mas'oolaa
English Translation
And do not approach the property of an orphan, except in the way that is best, until he reaches maturity. And fulfill [every] commitment. Indeed, the commitment is ever [that about which one will be] questioned
