Quran 4:5 from Surah An-Nisaa on Divine Marvels.
وَلَا تُؤۡتُواْ ٱلسُّفَهَآءَ أَمۡوَٰلَكُمُ ٱلَّتِي جَعَلَ ٱللَّهُ لَكُمۡ قِيَٰمٗا وَٱرۡزُقُوهُمۡ فِيهَا وَٱكۡسُوهُمۡ وَقُولُواْ لَهُمۡ قَوۡلٗا مَّعۡرُوفٗا
English translation: And (do) not give the foolish your wealth which (was) made (by) Allah for you a means of support (but) provide (for) them with it and clothe them and speak to them words (of) kindness
Transliteration: wala tu'tu al-sufahaa amwalakumu allati ja'ala al-lahu lakum qiyaman wa-ur'zuquhum fiha wa-ik'suhum waqulu lahum qawlan ma'rufan
