QUESTION
Is it permissible for a Salafee to work as a groundskeeper for a masjid run by the people of innovation, specifically the masjids of the Qutbees and Suroorees? Can he also work in their administration?
ANSWER
by Shaykh Rabee' ibn Haadee Al-Madkhalee, well-known scholar and retired professor from the Islaamic University of Al-Madeenah
If he does not have access to a Salafee masjid where he can pray with the Salafees, then he may pray with them. But if Allaah favors him by having a Salafee masjid nearby, a masjid whose imaam is a Salafee, then he must try his very best to offer his prayers there and stay away from the masjids of the people of innovation in general.
Regarding working for them in their administration, then their administration is usually harmful to the Muslims and to Islaam itself sadly enough. So I do not see it as being permissible to work with them in administrative tasks, as cooperation with them is usually considered cooperation upon sin and transgression, especially since they focus their efforts against the Salafees more than anyone else.
[ The shaykh was then asked, "And what about other than administrative work, like groundskeeping for example? ]
If he is free to choose, then I don't see that as being permissible. They would not offer work to a Salafee anyway.
