Quran 4:5 — Women (Al-Nesa')

Do not give immature orphans the properties that GOD has entrusted with you as guardians. You shall provide for them therefrom, and clothe them, and treat them kindly.

[4:4] You shall give the women their due dowries, equitably. If they willingly forfeit anything, then you may accept it; it is rightfully yours.

[4:6] You shall test the orphans when they reach puberty. As soon as you find them mature enough, give them their property. Do not consume it extravagantly in a hurry, before they grow up. The rich guardian shall not charge any wage, but the poor guardian may charge equitably. When you give them their properties, you shall have witnesses. GOD suffices as Reckoner.
