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?

Using the empty space of a waqf property for performing Salaah

Q: A property had been made waqf with the intention that the income be utilised for various charity purposes. Presently there is a dire need for a at least a Musallah where the local Muslim brothers can offer daily 5 salaahs. The waaqif is willing to make a supplementary Deed to incorporate the establishment of a Musallah on the empty terrace of the building he had donated. Is this ok and can one perform Jummah salaah and also tarawih and Eid salaah in addition to the daily 5 times salaah in such a place?
