Status of nikaah if a man lied to a girl just to get married to her

Q: If a woman marries a man based on what he told her and later on she finds out that the man was untruthful, meaning he lied about everything just to get her to marry him. Is the nikaah invalid? Especially if he lied about being a practising Muslim which it turned out that he wasn't? Does she need to do iddat even if she only stayed with him for a week and she didn't engage in intercourse because she was on her period with this untruthful man?

Investing in an electrical store

Q: I am from a Muslim country. I am planning to invest in a business with a friend in which the friend of my father repairs electronic equipment like fans, washing machines, ovens, irons, etc. and also installs electricity in newly built houses and sells electric items.

My question is that is this type of business halal as we provide our service and the user of all these things will use them for some haraam things like they will watch movies, listen to music and this kind of stuff. In general, is an electric store business permissible?

Performing salaah at home if there is social distancing in one's masjid

Q: With the distances of one meter at the Masjid, some people prefer to perform their salaat in jamaat in other private places (like in a house) with their shoulders together. They perform the five salaat and the jumuah salaat in houses with their shoulders together? Is it correct? Or is it better for these people to come to the Masjid ?

Wife sleeping in another room without the consent of her husband

Q: What is the status of a woman (wife) if she (after getting annoyed because of a minor domestic issue) on herself starts separating her bed from her husband and starts sleeping in another room without the consent of her husband? Does Shariah allow her to do so?

If not, then what are the consequences? Somebody told me that they have to renew the nikaah as the wife is claiming that she is not interested in having any physical relation with her husband. 

Wazeefah to fulfill one's needs

Q: Could you please confirm if the below is valid and is there any authentic Hadith regarding this:

It is mentioned in the Hadith that the solution to all problems lie in Surah Faatiha. How to read it:

In between the sunnah and fard of Fajr Salaah, recite

Durood Ebrahim 11 times
Surah Faatiha 41 times
Durood Ebrahim 11 times

Each time you recite Surah Faatiha, you will join bismillah's last Meem with Surah Faatiha's Laam like this,

Bismillah hir rahman nir rahee mil hamdo lilahi rabbil aalimeen.

Here I have joined the the end of “bismillah with the alhamdolillah. So it becomes MIL. Then you will repeat "ar rahman nir raheem"… 3 times (each time you recite Surah Fatiha) and aameen 3 times. (Each time you recite surah fatiha)

For every problem, every hajat it works like fire. Whatever you want will happen with 7 days or longer. There is no way that your hajat will not happen. It's guaranteed. Please continue it until your hajat is given.

Is all this authentic?

Facing the qiblah while being intimate with one's wife

Q:

1. When I am intimate with my wife, we sometimes face the qiblah while kissing, hugging, rolling on bed, etc. But we are nude and we face the qiblah. Though we try to avoid it sometimes. Is is a sin to face the qiblah when nude, whether from the front side or back.

2. Although we know that we should put a sheet over ourselves while being intimate but sometimes knowingly we do it without a sheet and towards the qiblah. Are we sinning? We know that while relieving oneself one should not face the qiblah and we don’t do it while relieving.
