Qur'ān 4:5 · An-Nisa (النساء)

وَلَا تُؤْتُوا۟ ٱلسُّفَهَآءَ أَمْوَٰلَكُمُ ٱلَّتِى جَعَلَ ٱللَّهُ لَكُمْ قِيَـٰمًۭا وَٱرْزُقُوهُمْ فِيهَا وَٱكْسُوهُمْ وَقُولُوا۟ لَهُمْ قَوْلًۭا مَّعْرُوفًۭا

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.
