Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ أَبِي إِسْحَاقَ قَالَ سَمِعْتُ الْبَرَاءَ يَقُولُ قَرَأَ رَجُلٌ الْكَهْفَ وَفِي الدَّارِ دَابَّةٌ فَجَعَلَتْ تَنْفِرُ فَنَظَرَ فَإِذَا ضَبَابَةٌ أَوْ سَحَابَةٌ قَدْ غَشِيَتْهُ قَالَا فَذَكَرَ ذَلِكَ لِلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ اقْرَأْ فُلَانُ فَإِنَّهَا السَّكِينَةُ تَنَزَّلَتْ عِنْدَ الْقُرْآنِ أَوْ تَنَزَّلَتْ لِلْقُرْآنِ.
English Translation
Muhammad ibn Ja'far told us: Shu'bah told us, from Abu Ishaq, who said: I heard al-Bara' say: A man recited Surat al-Kahf while there was a riding animal in the house, and it began to shy in fright. He looked, and there was a mist or a cloud that had enveloped him. They said that this was mentioned to the Prophet, peace and blessings be upon him, and he said, "Recite, so-and-so, for it is the tranquility (sakinah) that descended at the Qur'an," or "descended for the Qur'an."
