الترمذي:٢٩٠٢حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ قَالَ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ أَبِي خَالِدٍ قَالَ أَخْبَرَنِي قَيْسُ بْنُ أَبِي حَازِمٍ عَنْ عُقْبَةَ بْنِ عَامِرٍ الْجُهَنِيِّ

عَنِ النَّبِيِّ ﷺ قَالَ قَدْ أَنْزَلَ اللَّهُ عَلَىَّ آيَاتٍ لَمْ يُرَ مِثْلُهُنَّ (قُلْ أَعُوذُ بِرَبِّ النَّاسِ ) إِلَى آخِرِ السُّورَةِ وَ (قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ ) إِلَى آخِرِ السُّورَةِ  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
