The Ruler Has Forbidden People From Smoking in Public Buildings- Disobeying Him in That is Treachery

Question :

The authorities have issued a ruling that prohibits people from smoking in government-owned buildings. Some building and office managers are taking this law seriously and are striving to enforce it; others go against it. Are those who go against this rule being deceitful against the trust that the authorities have given them?

Answer:

These people who do not adhere to the order are deceitful A with their trust and committing two acts of disobedience. The first is smoking, which is unlawful because of the grave harms that result from it, and because of the intoxication it sometimes causes.

The second is disobeying those in authority, who have forbidden employees from committing this sin. Allah Almighty says:
"O you who believe! Obey Allah and obey the Messenger, and those of you (Muslims) who are in authority."

The Prophet ﷺ said:
"Whoever obeys me has obeyed Allah; whoever disobeys me has disobeyed Allah. Whoever obeys the 'Amir (leader or ruler) has obeyed me, whoever disobeys the 'Amir has disobeyed me."

Recorded by Al-Bukhari and Muslim, this is the wording of Muslim.

This Hadith means that it is obligatory to obey the 'Amir in what is good because the Prophet ﷺ said:
Indeed, obedience is in what is good."
