Is what Ibn Khaldun mentioned in his Muqaddimah about "Al-Halumiyyah" and seeing loved ones in dreams by reciting foreign names before sleep true?

Ibn Khaldun mentioned in "The Muqaddimah" the practice of "al-Halumah," which involves uttering foreign words before sleep to induce a vision revealing desired matters. He attributed it to the practitioners of spiritual exercises (Sufis). He experimented with it and found it effective, asserting that this was due to the soul's preparation.

However, these practices are not supported by any legal or rational evidence, and they are among the means of acquiring knowledge through which Satan misleads people.

Shaykh al-Islam Ibn Taymiyyah clarified that many who claim spiritual unveiling believe that their spiritual exercises purify their souls, causing their erroneous beliefs to manifest as if they were true unveilings.

This practice is pagan in origin and very ancient in the Near East, where it was part of rituals to obtain revelation or healing by sleeping in sacred places, reciting specific incantations, and offering sacrifices, as found in Sumerian and Babylonian texts, and ancient Arabic inscriptions in Yemen and elsewhere.

The fatwa (definition) concluded by prohibiting this practice for two reasons: 1. Believing something to be a cause for something else without legal or rational evidence, which is a form of shirk (definition) (associating partners with Allah) in means. 2. Imitating pagans in their actions, especially since its foreign words may contain shirk or kufr (disbelief).
