Quran An-Nisa 4:5

وَلَا تُؤۡتُواْ ٱلسُّفَهَآءَ أَمۡوَٰلَكُمُ ٱلَّتِي جَعَلَ ٱللَّهُ لَكُمۡ قِيَٰمٗا وَٱرۡزُقُوهُمۡ فِيهَا وَٱكۡسُوهُمۡ وَقُولُواْ لَهُمۡ قَوۡلٗا مَّعۡرُوفٗا

Translation

And do not give the weak-minded your property, which Allāh 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.
