question #1 Sahih Muslim 161a, Book 1, Hadith 311 : What was the significance of the angel’s appearance to the Prophet Muhammad (ﷺ) during the intermission of revelation?

Wrap me up, wrap me up! So they wrapped me up, and the Blessed and Most Exalted Allah sent down:” You who are shrouded, arise and deliver warning, your Lord magnify, your clothes cleanse, and defilement shun,” and” defilement” means idols; and then the revelation was followed continuously.
