Jabir bin Abdullah [may Allah be pleased with him] said: “I heard the Messenger of Allah (ﷺ) – and he was narrating about the pause in Revelation – so he said in his narration: “I was walking, when I heard a voice from the heavens. So I raised my head, and there was an angel, the one that had come to me at Hira, sitting upon a chair between the heavens and the earth. I fled from him out of fear, and I returned and said: ‘Wrap me up! Wrap me up! So they covered me.” Then Allah, Most High revealed: ‘O you who are wrapped up! Arise and warm.’ Up to His saying: ‘And keep away from the Rujz!’ before the Salat was made obligatory.”
