Muhammad was terrified
Muhammad was terrified: He was extremely scared. He ran back to his home. He was trembling. He told his wife Khadijah what happened to him and asked her to cover him. She told him that God would not let him down or allow devils to touch him as he kept good relations with his relatives, helped the poor people and liked doing charity.
A divine revelation or satanic whisperings? Muhammad was afraid that he was possessed by evil. He went with his wife Khadijah to tell the whole story to Waraqa Bin Nawfal (a relative of Khadijah) who was a religious Christian person and knowledgeable in the Bible.
Waraqa predicted that Muhammad would be a Prophet and assured him that what he experienced was a divine revelation similar to what Moses the Prophet of Jews received. Waraqa wished to support Muhammad but he was very old at that time. He told Muhammad that he would be driven out of Makkah by his own people and would be treated with hostility by some people.
