Quran 4:2 — Women (Al-Nesa')

You shall hand over to the orphans their rightful properties. Do not substitute the bad for the good, and do not consume their properties by combining them with yours. This would be a gross injustice.

[4:1] O people, observe your Lord; the One who created you from one being, and created from it its mate, then spread from the two many men and women. You shall regard GOD, by whom you swear, and regard the parents. GOD is watching over you.*

[4:3] If you deem it best for the orphans, you may marry their mothers—you may marry two, three, or four. If you fear lest you become unfair, then you shall be content with only one, or with what you already have. Additionally, you are thus more likely to avoid financial hardship.
