Stand out firmly for justice as witnesses to Allah even as against yourselves or your parents or your kin and whether it be (against) rich or poor: for Allah can best protect both. Follow not the lusts (of your hearts) lest ye swerve and if ye distort (justice) or decline to do justice verily Allah is well acquainted with all that ye do.

Qur'an

Sura 4 Ayats 128 – 129
"If a wife fears cruelty or desertion on her husband's part there is no blame on them if they arrange an amicable settlement between themselves; and such settlement is best; even though men's souls are swayed by greed. But if ye do good and practice self-restraint Allah is well acquainted with all that ye do.”

"Ye are never able to be fair and just between women even if it is your ardent desire: but turn not away (from a woman) altogether so as to leave her (as it were) hanging (in the air). If ye come to a friendly understanding and practice self – restraint Allah is Oft-Forgiving Most Merciful”

Sura 16 Ayat 90
"Allah commands justice the doing of good and liberality to kith and kin and He forbids all shameful deeds and injustice and rebellion: He instructs you that ye may receive admonition”

Sura 4 Ayat 19
"O ye who believe! Ye are forbidden to inherit women against their will. Nor should ye
treat them with harshness, that ye may Take away part of the dower ye have given them, except where they have been guilty of open lewdness; on the contrary live with them on a footing of kindness and equity. If ye take a dislike to them it may be that ye dislike a thing, and Allah brings about through it a great deal of good."
