FORBIDDEN IN MARRIAGE

Surah: An Nisa Ch:4 V:22, 23, 24

And marry not women whom your fathers married, except what has already passed; indeed it was shameful and most hateful, and an evil way.

Forbidden to you (for marriage) are: your mothers, your daughters, your sisters, your fathers sisters, your mothers sisters, your brothers daughters, your sisters daughters, your foster mother who gave you suck, your foster milk suckling sisters, your wives mothers, your step daughters under your guardianship, born of your wives to whom you have gone in - but there is no sin on you if you have not gone in them (to marry their daughters), - the wives of your sons who (spring) from your own loins, and two sisters in wedlock at the same time, except for what has already passed; verily, Allah is
OftForgiving, Most Merciful.

Also (forbidden are) women already married, except those (captives and slaves) whom your right
hands possess. Thus has Allah ordained for you. All others are lawful, provided you seek (them in
marriage) with Mahr (bridal money given by the husband to his wife at the time of marriage) from your property, desiring chastity, not committing illegal sexual intercourse, so with those of whom you have enjoyed sexual relations, give them their Mahr as prescribed; but if after a Mahr is prescribed, you agree mutually (to give more), there is no sin on you. Surely, Allah is Ever AllKnowing, AllWise.
