What is the ruling of Islamic Law on working in hotels?
All praise is due to Allah, and peace and blessings be upon our master, the Messenger of Allah.
It is permissible to work in hotels, restaurants, and shops in jobs that involve no direct handling of forbidden things and do not assist in them, such as administrative work.
As for jobs in which one directly handles forbidden things or assists in them, such as serving, transporting, or purchasing alcohol, receiving payment for it, or agreeing to buy it, working in them is forbidden, based on the saying of Allah the Mighty and Majestic: “And cooperate in righteousness and piety, but do not cooperate in sin and aggression. And fear Allah; indeed, Allah is severe in penalty.” [al-Māʾidah/2]
The basic nature of the work of hotels and restaurants is permissible, and the sin of any forbidden element that arises incidentally in some of what takes place in a hotel or restaurant is borne by those who run it.
The scholars have also permitted dealing with one whose lawful wealth is mixed with unlawful wealth, as previously explained in Fatwa no. (
