Questions on the Explanation of the Book of Nullifiers of Islam

Question:
One of the brothers has a commercial establishment, and a man works with him whom he discovered to be a Sufi. The question is: what is the obligatory action toward this Sufi? Is he to be called to Islam, or is he to be expelled from this job?

Answer:
He is a Muslim, but he has a religious innovation (bid'ah). All of Sufism is a religious innovation. Not every Sufi is a disbeliever. One is not declared a disbeliever unless he reaches the level mentioned by the Shaykh, where he exceeds the Shari'ah of Muhammad (peace and blessings be upon him), such as Ibn Arabi, al-Hallaj, and others. As for mere Sufism, it is a religious innovation and not disbelief. So keep him and keep him with you, and call him to the Sunnah and to abandoning Sufism. Read books to him or give him books, perhaps Allah will guide him through you.
