The rights of the husband and wife

Q: I have heard some saying including few scholars saying that a husband's rights over his wife are greater than her rights over him. Is that true and why/why not? I am finding this saying a bit strange because in the Quran it says that wives have similar rights over their husbands to what is reasonable. Islam teaches that both have equal rights, some of their rights are identical but some rights are different, and the husband's rights are not more important than the wife's rights, rather both the rights of the husband and wife are of equal importance. Can you please explain, is the saying mentioned above true and if it is true, then why is it true? Because it seems to contradict islamic teachings.

Renting a property to people whose dealings are doubtful

Q: My father in law owns a building, all the portions being given on rent. Though the land belongs to my husband but he is not given any amount nor has he ever demanded as he is having a good job and my father in law's only source of income is the rent from the building.

The rented places are.... A bank, an MRI CT scan service, a gym, a gents salon, a female beauty parlor, a tobacco shop, and an estate agency.

1. I want to know if the income in the form of renting to these places is permissible?

2. When we stay at our in laws, can we eat the food bought with the same money?

3. If one qurbaani share in a cow is purchased with the abovementioned income, will it have an effect on the other shares of qurbaani?
