Because of some floods some parts of Ka'bah was destroyed. The tribes repaired the walls and it was time to install the Hazarul-Aswad in its place. Each tribe wanted to acquire this honor so a war was near to take place until Abu Umayyah the oldest man in the Quraish tribe suggested that we should let the first man who enters the Masjidul-Haraam decide what to do in this regard. Muhammad s.a.w.a was that man and he was known for his honesty and authenticity among the people of that time.

Anyway, it seems that your question deals with the regulations of Riba(usury)
So if the owners of the mentioned company are not Muslims, you can invest your money and take interest from them.

To be more precise we have to say that a woman has to obey her husband in "not leaving the house without his permission".
She can use other means of communication for doing Silatu-l-arhaam i.e. to odserve her duty of having relationship with the blood-related family members, like in social media or through phone calls...
And in cases that she is outside the house and does not need her husband's permission,she can have an appointment to visit them.
So a man can never prohibit her from seeing her relatives or speaking to them.

It is also narrated in Nuzhatul Majalis wa Muntakhabu-nafa'es for Abdurrahman Safouri Shafe'ee who is also a Sunni Scholar.

It depends on the law of your country. But according to the sharia court they don't take your son if your husband is not Muslim.

Yes. Now most of ulama believe non-Muslims who believe in God are clean. Just if they cook halal chicken with pork in one dish, then it is najis and you should not eat. 

No
