Taking pilgrims to visit such places where Bid`ahs are committed

Q: My brother takes pilgrims who come to Madinah to some sanctuaries, which include unallowable places such as Al-Masajid Al-Sab`ah, `Uthman Well, Al-Dud Well, Turbat Al-Shifa', Masjid Al-`Arid and other places like Masjid Al-Qiblatayn. He gets fees from the pilgrims or their supervisor in return for that and they agree to the fees before moving. Is this work permissible in Shari`ah (Islamic law)? Are these fees lawful? Please, give us a detailed Fatwa (legal opinion issued by a qualified Muslim scholar) concerning that, may Allah reward you with the best!

A: What your brother does of leading pilgrims and those performing `Umrah (lesser pilgrimage) to places in Al-Madinah that are unallowable for visiting, such as Al-Masajid Al-Sab`ah, is not permissible and the money he receives in return is Haram (ill-gotten) money. You should advise him to leave this work. If he does not obey, you should report him to the Committee for the Propagation of Virtue and the Prevention of Vice to deal with him.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
