Are the daily remembrances (adhkar) sufficient for protection from envy, or is daily Ruqyah necessary, and what is the correct way to perform Ruqyah?

Remembrances (dhikr) are a means of protection from harm and injury, including envy. There are other protective measures mentioned by Ibn Al-Qayyim. Ruqyah Shar'iyah (Islamic incantation) is permissible for an afflicted or non-afflicted person. One can perform it for oneself or seek it from people of Sunnah and righteousness who are far removed from charlatanry.
