It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: I secluded myself in the Cave of Hira for a month. When I completed this period and descended to the open area of the valley, I was called. I looked in front of me, behind me, to my right, and to my left, but I saw nothing. Then I was called again. I looked in the same way, but I could not see anyone. Then I was called again. This time, when I raised my head, I saw that the angel was sitting on a throne in the air. In another narration: He was sitting on a throne between the heaven and the earth. This caused me to tremble severely. I went to Khadijah and said: Cover me with a blanket. So they covered me with a blanket and poured water over me. Then Allah Almighty revealed these verses: O you who are wrapped in a blanket, arise and warn, and magnify your Lord, and purify your garments.
