Quran 4:3 — Women (Al-Nesa')

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.

[4:2] 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.

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