"Then the angel caught me (forcefully) and pressed me so hard that I could not bear it... Then he released me and said, ‘Read!'... I returned to Khadijah trembling with fear and said, ‘Cover me! Cover me!'"
The terror Muhammad felt contrasts with the calm assurance given to biblical prophets when encountering God's angels
Muhammad reportedly recited verses honoring al-Lāt, al-‘Uzzā, and Manāt, which he later retracted, saying: "Satan cast upon my tongue words I did not intend."

Sahih al-Bukhari, Book 71, Hadith 658 (also in Sahih Muslim, Book 26, Hadith 5436):
