The ruling on dhikr and supplication that goes beyond the Book and the Sunnah?

Question:
If a person has a daily routine of dhikr after Fajr and after Maghrib from the Book of Allah and the Sunnah of His Messenger (peace and blessings be upon him), is there any prohibition in that, even if it is not transmitted? I mean: he adds to what is transmitted from the Book of Allah and the authentic Sunnah?

Answer:
If one adds to the dhikr and supplications, there is nothing wrong with it, but if one focuses on what is transmitted and does more of that, it is better. However, if one adds supplications from oneself that one needs, or uses words of dhikr that are not transmitted, there is nothing wrong with it. For example: "Subhan Allah al-Azim al-Jalil al-Quddus al-Malik al-Rahman" (Glory be to Allah, the Great, the Majestic, the Holy, the King, the Merciful), "Subhan Allah al-Azim al-Shan" (Glory be to Allah, the Great in status), "Subhan Allah al-Qadir 'ala Kulli Shay'" (Glory be to Allah, the Able to do everything), even if it did not come in a hadith; there is nothing wrong with it, for all of it is glorification and exaltation.
Q: And if this daily routine is used as ruqyah (healing by Qur'anic recitation), and it has been beneficial in many matters for healing from some diseases, is it permissible to use it without any prohibition?
A: There is nothing wrong with it, there is nothing wrong with it, I do not know of any harm in it.
