It is the house of worship of the Jews. Whoever sees in his dream that there is a synagogue in his home, his view on predestination resembles the view of the Jews. Likewise, if he sees that his home is a synagogue, or sees that his home was turned into a synagogue, he will rebel along with a rebel leader. If he sees that he is in a synagogue, his doctrine is the doctrine of the Jews. If he sees that he is being installed [or: setting something up] in a synagogue, he is searching for an innovation. The synagogue in a dream points to philosophy, abrogated sciences and physicians. If he takes charge in it, or sees himself in the dream doing what its people do, it indicates associating with Jews or with those who take on their manners, or inclining toward their doctrine, or breaking his pledge of allegiance; just as, if he did that in their church, it would indicate his associating with Christians, adopting their doctrine or siding with them. If he sees the mosques demolished, it indicates the designs [hums] of the enemy and their victory over the Muslims. The synagogue [bi'a] may indicate a pledge of allegiance [bay'a] upon fear of God the Exalted and obedience to Him.
