Hadith 18637

حَدَّثَنَا حُجَيْنٌ ، حَدَّثَنَا إِسْرَائِيلُ ، عَن أَبِي إِسْحَاقَ ، عَنِ الْبَرَاءِ ، قَالَ : بَيْنَمَا رَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُصَلِّي ، وَفَرَسٌ لَهُ حِصَانٌ ، مَرْبُوطٌ فِي الدَّارِ ، فَجَعَلَ يَنْفِرُ ، فَخَرَجَ الرَّجُلُ ، فَنَظَرَ ، فَلَمْ يَرَ شَيْئًا ، وَجَعَلَ يَنْفِرُ ، فَلَمَّا أَصْبَحَ ، ذَكَرَ ذَلِكَ لِلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فَقَالَ : " تِلْكَ السَّكِينَةُ نَزَلَتْ بِالْقُرْآنِ " .
It is narrated from Hazrat Bara’ (may Allah be pleased with him) that a man was reciting Surah Al-Kahf, and there was an animal (a horse) tied in the house. Suddenly, it started to get restless. The man looked and saw a cloud or canopy that was covering him. He mentioned this to the Noble Prophet (peace and blessings be upon him), so the Noble Prophet (peace and blessings be upon him) said, "O so-and-so! Keep reciting, for that was tranquility (sakinah) which descends at the time of the recitation of the Noble Qur’an."
