Wazifah for repelling bad thoughts before sleeping

Q: My grandmother who is a widow has asked me to ask this particular question to you:

She has asked for any wazaif or any specific azkaar to be recited as she is saying that before bedtime in the night she gets some bad thoughts. She said "aise taise galat galat khayaal aate rehte hai"...I don't exactly know what she means by it but she regularly recites prayers and azkaar and Quran before bedtime. Kindly help with some azkaar/wazaaif.

Who should participate in the ghusl of a deceased person?

Q:

1. Who should participate in the ghusl of a deceased person? Should it be done by the experienced people of the burial society, or should the relatives do it? What does the Sharia and Sunnat prefer?

2. A person gives a directive while living that his children should not do his ghusl because it will be an emotional/traumatizing experience for them and it is better done by strangers. Is this thinking correct?

Missing one day of kaffaarah fast due to traveling

Q: I broke a fast in Ramadhaan due to intercourse. I am making it up by fasting 60 days. I haven't finished it yet, with the menstrual cycles in between, I have only fasted 40 days so far. I have to go on a 1 day trip regarding one of my degree courses. I will travel from the morning, visit a site then travel back the same day during the day around or close to maghrib. Can I not fast this day and then continue towards my 60 day goal (reason: travel)? Or what is the ruling towards it?

Loyalty club members receiving discounts and entry into competitions

Q: There is a loyalty club business where you pay for a yearly membership and get discounts on a variety of stores. The company also gives you free entries into bi monthly prize draws to win a car, etc.

Since we are not paying money for the entries but are paying for the membership, will it be considered halaal if we win a prize?

Helping one's husband quit vaping

Q: My husband recently started smoking vape and has been doing it secretly. I've suspected it a few times and asked him, and he denied it. It started troubling his conscience and he eventually told me about it. I was very disheartened because he never used to do those sort of things and he knows how much I hate it. He said that I must please help him stop the habit.

Can Mufti please advise me on how to go about helping him? He stopped for about 2 months and today I found that he started again. I dont know what to do as I dislike it so much and feel very uncomfortable with it.
