Surah Al-An'am, Verse 152

وَلَا تَقۡرَبُواْ مَالَ ٱلۡيَتِيمِ إِلَّا بِٱلَّتِي هِيَ أَحۡسَنُ حَتَّىٰ يَبۡلُغَ أَشُدَّهُۥۚ وَأَوۡفُواْ ٱلۡكَيۡلَ وَٱلۡمِيزَانَ بِٱلۡقِسۡطِۖ لَا نُكَلِّفُ نَفۡسًا إِلَّا وُسۡعَهَاۖ وَإِذَا قُلۡتُمۡ فَٱعۡدِلُواْ وَلَوۡ كَانَ ذَا قُرۡبَىٰۖ وَبِعَهۡدِ ٱللَّهِ أَوۡفُواْۚ ذَٰلِكُمۡ وَصَّىٰكُم بِهِۦ لَعَلَّكُمۡ تَذَكَّرُونَ١٥٢

And do not approach the orphan's property except in a way that is best [i.e., intending improvement] until he reaches maturity. And give full measure and weight in justice. We do not charge any soul except [with that within] its capacity. And when you speak [i.e., testify], be just, even if [it concerns] a near relative. And the covenant of Allāh fulfill. This has He instructed you that you may remember.
