Arabic (Original)
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.
English Translation
Hujayn narrated to us: Isra'il narrated to us, from Abu Ishaq, from al-Bara', who said: While a man from among the companions of the Prophet, peace and blessings be upon him, was praying, and his stallion horse was tethered in the courtyard, it began to bolt. The man went out and looked but saw nothing, yet it kept bolting. When morning came he mentioned that to the Prophet, peace and blessings be upon him, and he said: 'That was tranquility (sakinah) descending because of the Qur'an.'
