Abandoning the ways of the Kuffaar

Q: My question is, how should we treat the act of sinning, specifically homosexuality amongst the non-believers. How are the non-believers suppose to be treated in an Islamic country, and what do we do if they are committing Zina and Homosexuality in a Muslim and Non-Muslim country? I believe Allah wants us to be merciful Alhumdulilah, but how are we suppose to perceive these acts done by non-believers? Do non-believers get the same punishment as a Muslim would if they practise Zina and Homosexuality in a Muslim country, and what if they do this in a non Muslim country like America? how should we go by this, since I live in a non-Muslim country, and I am a convert Alhumdulillah.

Doing an accounting job

Q: Is it permissible in Islam to have an accounting job? Or a financial analyst? Every company nowadays deals with interest. So avoiding it

Istihalah

Eating more than one time a day

Q: It is sunnah to eat one meal a day. But the method of meal is (any of the regular occasions in a day when a reasonably large amount of food is eaten) and so in my breakfast I only eat a bowl of cereal or 2 toast with milk so is it considered a meal because it is less than lunch or dinner and it's not a reasonably large amount?

Dream

Q: I saw a house in my dream, the house was new and I was alone in it. Roaming around or playing I guess. There was a garden outside and it was raining pleasantly outside the house. I was protecting a wooden door from rain water, I don't know whose house it was but it was big and beautiful well furnished. I saw a Quran folded in red golden cloth on the table and I was holding house key in my hand.

Dream

Q: I saw a dream, can you please interpret it. The dream is as follows:-

My younger brother came to me running and said mummy is going somewhere. So I went to mummy's room and asked her where are you going. She was wearing her hijab (black abhaya) and was ready to go, she said I am taking your sister to someone to make dua for her. I said what happened to her, where is she? My mummy replied she is in the guest room. I went there and I saw her sitting alone on a sofa, I approached her and recited LA-ILAHA-ILLALAH (FIRST PART OF KALIMA) SHE WAS SHOCKED AND JUMPED ON THE OTHER PORTION OF SOFA. I recited the kalima again and she was eased and then she hugged me and started crying. I eased her and she was crying.
