Ruling on giving the father a medicine to quit smoking without his knowledge

Question:

My father smokes tobacco, but we have found a drug that will rid him of this habit forever. The drug will cause him to be ill for two or three days; is it permissible for me to give it to him without his knowledge? You should bear in mind that he refuses to take it, while smoking causes him a number of problems.

Answer:

Smoking tobacco is Haram (prohibited) for it causes great harm and has no benefit at all. Whoever smokes should give it up and repent of it. As for your father, you should advise him. Concerning giving him a drug that makes him ill for two days in order to give up smoking, this is not permissible without his knowledge. Allah knows best.

May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
