Working and studying Deen

Q: I am currently studying ACCA. There are 5 members ( parents, 2 sisters and me ) in my family. My 2 sisters will marry in future and they will leave our house. By the grace of Allah, few years ago our residential property converted to commercial property and because of this we can earn a good amount of rental income. My mother is saying that I will have to do job after completing ACCA. But my plan is to spend my life participating in religious activities like tableeg, serving my parents and humanity, praying, doing Hifz e Quran and becoming an Alim from Darul Ilm Birmingham's online Alim course. I don't want to do job because if I do job then I will not be able to devote myself enough for a high rank in Jannah (Jannatul Firdous). Its my wish to attain high level of Jannah. If I don't do the job then my mother will become angry and disheartened. But I don't agree with her because rental income is enough for a good life and there is no need of mine to do job. I think that Allah has granted the property so that I can use my time in a good way. Please advise on this. I am quite depressed.

Hurmat-e-musaaharah

Q: I just want to ask a question, does thoughts and images in your mind constitute hurmat-e-musaaharah. E.g when I want to hug my dad as a father or shake my hand I am scared to touch him because I remember hurmat-e-musaaharah and I don't want my nikah or my dad's nikah to be broken, so I get these thoughts of him. But I don't have no lustful feeling for him but I am scared. Second I am scared to have children. If I have a son and I have to kiss him as a mother even after he gets bigger or he holds me, I am worried about hurmat musaaharah. As a parent I would I like to love my kids and my parents. But what do I do with theses thoughts in mind. What is lust for a woman. I love my husband so much of course I don't have any feeling for my dad but I just have these thoughts.

Impure clothes touching the exterior of the washing machine

Q: While putting clothes with najaasat on them in the washing machine, some of the clothes touched the outside of the machine. After washing, while taking out wet washed clothes, some part of the clothes touched the same spot of machine where najis clothes touched. My question is, did my wet clean clothes again became najis and should I wash them again?
