Jami` at-Tirmidhi Book 47, Hadith 377
“I heard the Messenger of Allah – 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.”
“The jinns used to ascent through the heavens, trying to listen about the Revealation. So when they heard a statement, they would add nine to it. The statement that they heard would be true, while what they added was false. So it was with the advent of the Messenger of Allah that they were prevented from their places. So they mentioned that to Iblis – and the stars were not shot at them before that. So Iblis said to them: ‘This is naught but an event that has occurred in the earth.’ So he sent out his armies, and they found the Messenger of Allah standing in Salat between two mountains” – I think he said “in Makkah” – “So they (returned) to meet with him (Iblis), and informed him. He said: ‘This is the event that has happened on the earth.’”
The Messenger of Allah said: “As-Sa’ud is a mountain of fire, a disbeliever will be rised upon it for seventy autumns, and them similarly he will fall down it, forever.”
