Correct translation of a Hadith regarding stray thoughts

Q: I wanted to know that if this Hadith talks about every kind of evil unwanted thoughts that come into mind and a person resists it or just related to religion?

Narrates Abdullah bin Abbas that, once, a person came to the Prophet and said, “Sometimes such wicked ideas come to my mind that I would prefer to be burnt down and reduced to charcoal than to give utterance to them.” The Prophet replied, “Praise be to Allah who turned back the matter towards thought sentiment.”

Selling wigs

Iddat after a forced marriage

Q: At age of 12, a girl's nikah was performed with her relative against her will as she was not wise. She did not accept him as her husbend. After 4 years, her mother sent her to her husband's house but at first night they had a conflict. She told her husband not to touch her. After 2 days she came back to her parents and lived there for 5 months. Then she got a divorce from her husband. Now the question is, does that girl have to sit for iddat before marrying another person or can she marry without sitting for iddat?

Performing one qurbaani for the whole family

Q:

1. Is one qurbani valid for whole family living under one roof?

2. I have heard that qurbani is wajib but I have seen many aalim's videos who say qurbani is Sunnat-e-Ebrahimi. So if a person does not do it, its not a sin as its a sunnah act, is it true?

3. I do not earn and I am dependent on my father but I did have some savings, was qurbani wajib on me though I gave that money to my mother 3 days before eid as I feared sin. 

Sister wishing to go for umrah while one is saving money for hajj

Q: I have been saving an amount for the purpose of Hajj (for me and my wife). Suddenly I have been asked by my elder sister to go for Umrah because she does not have any other mehram. Knowing Hajj is Farz while Umrah is Nafil, is it permissible for me to perform Umrah before Hajj with the amount I had saved. (My sister has already performed Hajj once with my father in the past but I have not).

Baseless narration about dua to read on Aashuraa

Q: Hazrat Zain-ul-Abideen (R.A) narrates that whosoever recites or listens to the recitation of the following dua anytime between sunrise and sunset on the day of 'Ashura, then it shall act as a guarantee for his life the following year and he shall not encounter death. If he was to experience death that year then he shall not be capable in reciting this dua by coincidence. My question is, is this narration authentic. The barelvi part of my family insists on its importance.
