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.
