the Prophet said: “Allah has revealed to me Ayat the likes of which have not been seen: “Say: I seek refuge in the Lord of mankind…” until the end of the Surat. “Say: I seek refuge in the Lord of Al-Falaq…” until the end of the Surat.

الترمذي:٣٣٦٧aحَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ إِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ حَدَّثَنِي قَيْسٌ وَهُوَ ابْنُ أَبِي حَازِمٍ عَنْ عُقْبَةَ بْنِ عَامِرٍ الْجُهَنِيِّ

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

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
