Reading inappropriate literature

Q: When I read something inappropriate (nothing like nudity, but text), something that a Muslim should not laugh at, I involuntarily have smirks? I have seized my jaw in the past (like tightened it) to stop myself as well as lightly biting my gums. Genuinely I don't want to laugh or smile, but frown if anything. So what do you think?

Muqaasamatul Jad

Q: I would like to know in our time in the baab of muqasamatul jad (مقاسمة الجد ) according to the ahnaaf on whose قول is the fatwaa given; on- Hazrat Abu Bakr Siddique (Radiyallahu Anhu), Imaam Abu Hanifa (Rahmatullahi Alayh), etc or Hazrat Zaid ibn Thaabit (Radiyallahu Anahu) , Imaam Abu Yusuf (Rahmatullahi Alayh), etc?

Painting the premises before leaving

Q: I used to work for an organization. The organization used to house all employees in flats or apartments. The rent as well as the levy, water and light bills used to be paid by them. It is stated in the lease contract of the apartment that upon leaving, the tenant should get the place painted. The organization did not mention to me, when I moved in, that I will have to bear the cost of the painting. To me, it was understood that the organization will bear the cost of painting the apartment as they used to bear all other costs. Is the cost of painting my responsibility or the responsibility of the organization?

Purchasing from Hindus

Q: I live in India and here Hindus have very different traditions like in front of the shops they smash some kind of fruits and lemons and coconuts and keep them at the corners of the entrance. So my question is am I allowed to go inside that shop and am I allowed to buy food products from that shop and I have also seen that shop has pictures of their idols and they do pooja over there. So sometimes used to eat from that shop. Was that haram and najis?

Q:

1) In salaah, if you move your head in any direction (right, left, up, down, back or forth), does this nullify the salaah?
