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.
