Sahih Muslim Book - 1, Hadith - 406

و حَدَّثَنِي أَبُو الطَّاهِرِ أَخْبَرَنَا ابْنُ وَهْبٍ قَالَ حَدَّثَنِي يُونُسُ قَالَ قَالَ ابْنُ شِهَابٍ أَخْبَرَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ أَنَّ جَابِرَ بْنَ عَبْدِ اللَّهِ الْأَنْصَارِيَّ وَكَانَ مِنْ أَصْحَابِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يُحَدِّثُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ يُحَدِّثُ عَنْ فَتْرَةِ الْوَحْيِ قَالَ فِي حَدِيثِهِ فَبَيْنَا أَنَا أَمْشِي سَمِعْتُ صَوْتًا مِنْ السَّمَاءِ فَرَفَعْتُ رَأْسِي فَإِذَا الْمَلَكُ الَّذِي جَاءَنِي بِحِرَاءٍ جَالِسًا عَلَى كُرْسِيٍّ بَيْنَ السَّمَاءِ وَالْأَرْضِ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَجُئِثْتُ مِنْهُ فَرَقًا فَرَجَعْتُ فَقُلْتُ زَمِّلُونِي زَمِّلُونِي فَدَثَّرُونِي فَأَنْزَلَ اللَّهُ تَبَارَكَ وَتَعَالَى { يَا أَيُّهَا الْمُدَّثِّرُ قُمْ فَأَنْذِرْ وَرَبَّكَ فَكَبِّرْ وَثِيَابَكَ فَطَهِّرْ وَالرُّجْزَ فَاهْجُرْ } [المدثر: 1-5] وَهِيَ الْأَوْثَانُ قَالَ: ثُمَّ تَتَابَعَ الْوَحْيُ.

Jabir bin 'Abdullah Al-Ansari - who was one of the Companions of the Messenger of Allah (s.a.w) - used to narrate that the Messenger of Allah (s.a.w), speaking of the interruption in the Revelation said: "While I was walking, I heard a voice from heaven. I raised my head, and there was the Angel who had come to me in Hira', sitting on a throne between heaven and earth." The Messenger of Allah (s.a.w) said: "I was stricken with terror, so I went back and said, 'Cover me, cover me!' So they covered me, then Allah, [Blessed be He and Most High], revealed the Verses: "O you enveloped in garments! Arise and warn! And magnify your Lord! And purify your garments! And keep away from Ar-Rujz!." - And that is the idols - "Then the Revelation resumed."
