He heard the Prophet ﷺ say, as he was speaking about the pause in revelation, "While I was walking, I heard a voice from the sky. I raised my eyes toward the sky, and there was the angel who had come to me at Hira, seated on a throne between the sky and the earth. I was terrified of him, so much so that I sank to the ground. I went to my family and said, 'Wrap me up, wrap me up.' Then Allah Almighty revealed, 'You who are wrapped in a cloak, arise and warn. And your Lord, magnify. And your garments, purify. And shun defilement' [Muddaththir 74:1–5]."
أنه سمع النبي ﷺ يقول وهو يحدث عن فترة الوحي: فبينا أنا أمشي، سمعت صوتا من السماء فرفعت بصري قبل السماء، فإذا الملك الذي جاءني بحراء قاعد على كرسي بين السماء والأرض، فجئثت منه حتى هويت إلى الأرض، فجئت أهلي فقلت: زملوني زملوني، فأنزل الله تعالى: {يأيها المدثر قم فأنذر وربك فكبر وثيابك فطهر والرجز فاهجر}.
Bukhari narrated it in the Beginning of Creation (3238), and Muslim in Faith (161:256), both from the hadith of Layth bin Saad, who said, Aqeel bin Khalid narrated to me, from Ibn Shihab, who said, I heard Abu Salama bin Abdul-Rahman say, Jabir bin Abdullah informed me, and he related the hadith, and the wording given is that of Bukhari.In Muslim's wording it says, "so I was terrified with fear because of it."Abu Salama said, "the rijz means idols," then the revelation grew intense afterward and continued steadily.His saying, "juithtu," means I was frightened and terrified. And his saying, "hawaytu," means I fell down.
