Gender Inequality in Islam
Before Marriage
To get married, a Muslim man must give dowry to his future wife. The bride-to-be does not have to give him anything.
Quran 4:4 And give the women (on marriage) their dower as a free gift; but if they, of their own good pleasure, remit any part of it to you, Take it and enjoy it with right good cheer.
During Marriage
During marriage, the husband must support his family. If he is able but doesn't give any money for the needs of the family, he sins. It's different on the part of the wife. She does not have to give any financial support. Even if she can but does not, she won't sin.
Quran 4:34 Men are the protectors and maintainers of women, because God has given the one more (strength) than the other, and because they support them from their means. Therefore the righteous women are devoutly obedient, and guard in (the husband's) absence what God would have them guard. As to those women on whose part ye fear disloyalty and ill-conduct, admonish them (first), (Next), refuse to share their beds, (And last) beat them (lightly); but if they return to obedience, seek not against them Means (of annoyance): For God is Most High, great (above you all).
Quran, 4:19 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 God brings about through it a great deal of good.
Quran, 4:20-21 But if ye decide to take one wife in place of another, Even if ye had given the latter a whole treasure from dower, take not the least bit of it back; Would ye take it by slander and a manifest wrong? And how could ye take it when ye have gone in unto each other, and they have taken from you a solemn covenant?
After Marriage
If they are divorced, the ex-husband would STILL have to support his ex-wife. It's still would be basically the same as they were married, except, no sex. The ex-wife does not have to give him anything. The ex-husband that does not pay alimony is going against the command of God.
Quran 2.241 For divorced women Maintenance (should be provided) on a reasonable (scale). This is a duty on the righteous.
