Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Then for some time the revelation paused for me. During that time, once I was walking (along the way) when I heard a voice from the sky. I raised my eyes towards the sky, and behold, the same angel who had come to me in the Cave of Hira was sitting on a chair (suspended) between the sky and the earth. Seeing this I became frightened, until I bent down towards the ground. I returned home and said to them: Wrap me up, wrap me up." Then Allah Almighty revealed these verses: "O you wrapped in garments! Arise and warn, and magnify your Lord alone, and keep your garments pure, and shun filth (al-rujz)" [Surah al-Muddaththir: 1-5]. Abu Salamah (may Allah have mercy on him) said: Al-rujz means the idols. He (peace and blessings be upon him) said: "Then after that the revelation became intense and came in succession."
