The reason for the fear of the Messenger (peace and blessings be upon him) when Jibril (peace be upon him) descended upon him for the first time

Question:
May Allah reward you, Your Eminence, father. The questioner asks: Is it correct that the reason for the fear of the Prophet (peace and blessings be upon him) when the revelation descended upon him and he said to Khadijah (may Allah be pleased with her), “Cover me,” was because he saw Jibril (peace be upon him) in the form in which Allah created him?

Answer:
No, but he was startled by something he had not experienced before. He was startled, may the prayers and blessings of Allah be upon him, by something he had not experienced before. It said to him, “Read,” and he had not read, nor did he read or write. For this reason, he responded and said, “I am not a reader.” So it covered him and said, “Read.” He said, “I am not a reader.” Then, the third time, after the third time, it said to him: So what startled him, may the prayers and blessings of Allah be upon him, was that something came to him that he was not accustomed to, and the angel came to him while he was alone in the mountain with no one around him. This is what frightened him, may the prayers and blessings of Allah be upon him.
