Is it permissible to say, "Verily, distress has afflicted me, and You are the Most Merciful of those who show mercy," seven times to dispel anxiety, as Ibn al-Qayyim mentioned in the book "Al-Fawa'id", quoting Ayyub (Job), peace be upon him?

The supplication of Ayyub (Job), peace be upon him: (Indeed, adversity has touched me, and You are the most merciful of the merciful) [Quran 21:83] combines the reality of Tawhid (definition) (Oneness of God), dependence on Allah, acknowledgment of the attribute of mercy, and seeking intercession through it. It has been experienced that reciting it seven times removes adversity. This falls under the category of ruqyah (definition) (incantation) and tested supplications. Ruqyah is not restrictive; rather, its original ruling is permissibility as long as it does not involve shirk (definition) (associating partners with Allah). It has been reported in the Sunnah (definition) what indicates the permissibility of tested ruqyahs if they do not contain shirk. The Prophet, peace and blessings be upon him, ordered that ruqyahs be presented to him, and he permitted those that did not contain shirk. He also commanded some of his companions to perform ruqyah with what they used to recite during the pre-Islamic era of ignorance, after purifying it from any shirk.
