Sahih Muslim | Book 1 | Hadith Number 305

Narrated by Jabir b. Abdullah
It is narrated on the authority of Jabir b. Abdullah that he heard the Messenger of Allah (may peace be upon him) says: The wahi was intermitted for me for a small span of time and while I was walking, and then the hadith like the one narrated by Yunus was transmitted but with the exception of these words: I was terror-stricken till I fell on the ground. Abu Salama said: Defilement means idols. After this the revelation was speeded up and followed rapidly.
