quran:4:5 –

And do not give the weak-minded your property, which Allah has made a means of sustenance for you, but provide for them with it and clothe them and speak to them words of appropriate kindness.  

But do not, O guardians, give to the foolish, the squanderers from among men, women and children, your property, that is, the property that is theirs but held by you, which God has assigned to you as maintenance (qiyāman, ‘maintenance’, is the verbal noun from qāma; a variant reading has qiyaman, the plural of qīma, ‘value’, that is, that with which property is valued), meaning that the property which sustains your livelihoods and the well-being of your children, lest they expend it improperly; provide for them thereof, that is, feed them from it, and clothe them, and speak to them decent words, prepare for them a kind reception, by giving them their property when they reach maturity.
القرآن:٤:٥ –

وَلَا تُؤْتُوا السُّفَهَاءَ أَمْوَالَكُمُ الَّتِي جَعَلَ اللَّهُ لَكُمْ قِيَامًا وَارْزُقُوهُمْ فِيهَا وَاكْسُوهُمْ وَقُولُوا لَهُمْ قَوْلًا مَعْرُوفًا  

{ولا تؤتوا} أيها الأولياء {السفهاء} المبذِّرين من الرجال والنساء والصبيان {أموالكم} أي أموالهم التي في أيديكم {التي جعل الله لكم قياما} مصدر قام أي تقوم بمعاشكم وصلاح أولادكم فيضعوها في غير وجهها وفي قراءة قيَما جمع قيمة ما تقوم به الأمتعة {وارزقوهم فيها} أي اطعموهم منها {واكسوهم وقولوا لهم قولا معروفا} عدوهم عدة جميلة بإعطائهم أموالهم إذا رشدوا.
