AHMAD 18591:
from al-Barāʾ b. ʿĀzib —
[Machine] There was a man reading Surah Al-Kahf in his house, and next to him was his horse tied to two stakes, until a cloud came and approached him. The cloud kept coming closer and closer until his horse became scared of it. The man said, "I was amazed by this." When morning came, he went to the Prophet ﷺ and mentioned this to him, narrating the story. The Prophet ﷺ said, "That was tranquility descending with the recitation of the Quran."

عن البراء بن عازب —
كَانَ رَجُلٌ يَقْرَأُ فِي دَارِهِ سُورَةَ الْكَهْفِ وَإِلَى جَانِبِهِ حِصَانٌ لَهُ مَرْبُوطٌ بِشَطَنَيْنِ حَتَّى غَشِيَتْهُ سَحَابَةٌ فَجَعَلَتْ تَدْنُو وَتَدْنُو حَتَّى جَعَلَ فَرَسُهُ يَنْفِرُ مِنْهَا قَالَ الرَّجُلُ فَعَجِبْتُ لِذَلِكَ فَلَمَّا أَصْبَحَ أَتَى النَّبِيَّ ﷺ فَذَكَرَ ذَلِكَ لَهُ وَقَصَّ عَلَيْهِ فَقَالَ النَّبِيُّ ﷺ تِلْكَ السَّكِينَةُ تَنَزَّلَتْ لِلْقُرْآنِ
