Sayyiduna Jabir bin Abdullah al-Ansari (may Allah be pleased with them both) heard the Prophet (peace and blessings be upon him) say: "Then the revelation stopped for some days. Once, while I was walking, I heard a voice from the sky. I raised my eyes towards the sky, and there was the angel who used to come to me, sitting on a chair between the sky and the earth. I was so terrified of him that I fell down to the ground. I came to my family and said to them: 'Wrap me up, wrap me up.'" So they wrapped him up, and Allah Almighty revealed these verses: "O you who are wrapped up! Arise and warn. And magnify your Lord. And purify your garments. And shun the rujz." [Surah al-Muddaththir: 1-5]
Abu Salamah said: Al-rujz means the idols. He (peace and blessings be upon him) said: "Then after that the revelation came, one after another."
