In the suburb where I live there is a Masjid that belongs to Sufis and another smaller Masjid belongs to them as well. Is it permissible to pray in it?.
Do not pray with these Sufis in their zawiyahs, and beware of keeping company with them and mixing with them, lest you be affected by what has affected them. Try to pray in the mosque of a congregation who seek to follow the Sunnah and are keen to do so.
And Allaah is the Source of strength. May Allaah send blessings and peace upon our Prophet Muhammad and his family and companions. End quote.
