as he was narrating about the period of Wahī (Revelation): "While I was walking, ˹suddenly˺ I heard a voice from the sky. I looked up and saw the same Angel who had visited me at the cave of Ḥirāʾ sitting on a chair between the sky and the earth. I got afraid of him, came back ˹home˺ and said, 'Cover me!' Then Allah ﷻ revealed: 'O you who covers himself [with a garment]' Arise and warn.' until His statement 'And idolatory, avoid.' (Muddaththir 74:1-5) After this the revelation started coming strongly, frequently and regularly."  

وَهُوَ يُحَدِّثُ عَنْ فَتْرَةِ الْوَحْىِ فَقَالَ فِي حَدِيثِهِ: «بَيْنَا أَنَا أَمْشِي، إِذْ سَمِعْتُ صَوْتًا مِنَ السَّمَاءِ، فَرَفَعْتُ بَصَرِي، فَإِذَا الْمَلَكُ الَّذِي جَاءَنِي بِحِرَاءٍ جَالِسٌ عَلَى كُرْسِيٍّ بَيْنَ السَّمَاءِ وَالأَرْضِ۔ فَرُعِبْتُ مِنْهُ فَرَجَعْتُ فَقُلْتُ زَمِّلُونِي! فَأَنْزَلَ اللَّهُ تَعَالَى {يَا أَيُّهَا الْمُدَّثِّرُ * قُمْ فَأَنْذِرْ}» إِلَى قَوْلِهِ «{وَالرُّجْزَ فَاهْجُرْ} فَحَمِيَ الْوَحْىُ وَتَتَابَعَ۔»
