If the situation is as mentioned - that is, the only Masjid in the village is controlled by followers of the
Tijaniyyah Sufi order who practice Bid`ah and superstitions, and that the righteous group has resisted their acts, but they have not responded; resulting in the righteous group leaving to establish a Masjid to offer prayers in ...Etc. Then, this Masjid is not Dirar.
Refuting the superstitions and Bid`ah of the Tijanys is an obligation on the knowledgeable people of Ahl Al-Sunnah wal-Jama`ah (those adhering to the Sunnah and the Muslim community). As for the degree of their Iman, and the ruling on what they have innovated of Bid`ah and superstitions; the Permanent Committee has prepared a written response regarding this issue.
Whoever has knowledge and feels that they will accept their advice may associate with them and (Part No. 2; Page No. 346) counsel them, hoping they will accept the advice and refrain from their Bid`ah, or at least some of their deviant practices. Otherwise, they (advisor) should shun them (the Tijanys).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
