What is the ruling on imposing a fine on workers if they smoke?

Question:
May Allah reward you. The honorable scholar says: I am responsible for an establishment that has shops, and I have implemented a system for all the shop owners. Yes. He says: I am responsible for an establishment. It has shops, and I have implemented a system for all the shop owners that imposes a fine of one hundred riyals on any of them who smokes inside the establishment. The question is: Is this exercise of independent legal reasoning (ijtihad) correct, even though it is a mercy from Allah in that many of them have quit smoking? And is it permissible to buy tapes or other beneficial items with this fine, or to put it into the establishment's fund?

Answer:
My brother, what are you doing with this action? The one who does not quit smoking, fire him and dismiss him, let him go, and do not fine him; because it is not permissible to take people's money without right. So, the one who does not abide by the condition, dismiss him and replace him, and praise be to Allah. And if he is fired from the job, he will be deterred and quit smoking without you fining him and taking his money. Yes.
