Qur'an 4:5
وَلَا تُؤْتُوا۟ ٱلسُّفَهَآءَ أَمْوَٰلَكُمُ ٱلَّتِى جَعَلَ ٱللَّهُ لَكُمْ قِيَـٰمًا وَٱرْزُقُوهُمْ فِيهَا وَٱكْسُوهُمْ وَقُولُوا۟ لَهُمْ قَوْلًا مَّعْرُوفًا
“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.”
