حَدَّثَنَا يَحْيَی بْنُ يَحْيَی أَخْبَرَنَا أَبُو خَيْثَمَةَ عَنْ أَبِي إِسْحَقَ عَنْ الْبَرَائِ قَالَ کَانَ رَجُلٌ يَقْرَأُ سُورَةَ الْکَهْفِ وَعِنْدَهُ فَرَسٌ مَرْبُوطٌ بِشَطَنَيْنِ فَتَغَشَّتْهُ سَحَابَةٌ فَجَعَلَتْ تَدُورُ وَتَدْنُو وَجَعَلَ فَرَسُهُ يَنْفِرُ مِنْهَا فَلَمَّا أَصْبَحَ أَتَی النَّبِيَّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ فَذَکَرَ ذَلِکَ لَهُ فَقَالَ تِلْکَ السَّکِينَةُ تَنَزَّلَتْ لِلْقُرْآنِ
