Sahih Bukhari Volume 6, Book 65, Hadith 4956

قَالَ مُحَمَّدُ بْنُ شِهَابٍ فَأَخْبَرَنِي أَبُو سَلَمَةَ، أَنَّ جَابِرَ بْنَ عَبْدِ اللَّهِ الأَنْصَارِيِّ ـ رضى الله عنهما ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَهْوَ يُحَدِّثُ عَنْ فَتْرَةِ الْوَحْىِ قَالَ فِي حَدِيثِهِ ‏"‏ بَيْنَا أَنَا أَمْشِي سَمِعْتُ صَوْتًا مِنَ السَّمَاءِ فَرَفَعْتُ بَصَرِي، فَإِذَا الْمَلَكُ الَّذِي جَاءَنِي بِحِرَاءٍ جَالِسٌ عَلَى كُرْسِيٍّ بَيْنَ السَّمَاءِ وَالأَرْضِ فَفَرِقْتُ مِنْهُ فَرَجَعْتُ فَقُلْتُ زَمِّلُونِي زَمِّلُونِي ‏"‏‏.‏ فَدَثَّرُوهُ فَأَنْزَلَ اللَّهُ تَعَالَى ‏{‏يَا أَيُّهَا الْمُدَّثِّرُ * قُمْ فَأَنْذِرْ * وَرَبَّكَ فَكَبِّرْ * وَثِيَابَكَ فَطَهِّرْ * وَالرِّجْزَ فَاهْجُرْ‏}‏‏.‏ قَالَ أَبُو سَلَمَةَ وَهْىَ الأَوْثَانُ الَّتِي كَانَ أَهْلُ الْجَاهِلِيَّةِ يَعْبُدُونَ‏.‏ قَالَ ثُمَّ تَتَابَعَ الْوَحْىُ‏.‏

Narrated Jabir bin 'Abdullah: While Allah's Apostle was talking about the period of pause in revelation. he said in his narration. "Once while I was walking, all of a sudden I heard a voice from the sky. I looked up and saw to my surprise, the same Angel as had visited me in the cave of Hira.' He was sitting on a chair between the sky and the earth. I got afraid of him and came back home and said, Wrap me! Wrap me!" So they covered him and then Allah revealed: 'O you, wrapped up! Arise and warn and your Lord magnify, and your garments purify and dessert the idols.' (74.1-5) Abu Salama said, "(Rijz) are the idols which the people of the Pre-Islamic period used to worship." After this the revelation started coming frequently and regularly.
