These verses, as well as certain others like

Then We sent to her Our spirit and it assumed for her the form of a perfect man. (19:17)

point, besides the attraction of spirits, to the fact that spirit beings may assume visible forms. However, what the Qur’an alludes to here is not modern necromancy,

which some so-called ‘civilized’ people practice by communication by magic with evil spirits who introduce themselves as spirits of the dead. Rather, it is as certain kinds of saints (like Muhy al-Din ibn al-‘Arabi) who, for a serious reason, communicate with good spirits whenever they want, make contact with them and form a relation with them, and by going to their abodes and to a degree drawing near to their atmosphere, benefit from their spirituality.
