What is religious tourism and what are its economic prospects?

The phrase "religious tourism" is a new term used to describe going to sacred places for Muslims and others. It includes Hajj, Umrah, visiting the Prophet's Mosque, visiting shrines and graves that are invoked besides Allah, as well as holy places for Jews, Christians, and others. This mixes faith with disbelief, and obedience with disobedience.

The Sharia has made an exception for three places to which it is permissible to undertake a journey with the intention of worship. These are mentioned in the Prophet's (peace and blessings be upon him) saying: "Journeys are not to be undertaken except to three mosques: this mosque of mine, the Sacred Mosque (Al-Masjid Al-Haram), and Al-Aqsa Mosque."

If the intent behind religious tourism is to assist those who wish to go for Hajj or Umrah, or to visit the Prophet's Mosque or Al-Aqsa Mosque, then working and investing in this is permissible and is among the acts of obedience for which one is rewarded, as it is assistance in goodness.

However, if the intent is to assist disbelievers and innovators in reaching their holy places, then working in this is forbidden because it involves aiding in disbelief or disobedience. Allah Almighty has prohibited this, saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression."
