The Messenger of Allah ﷺ said, "Shall I guide you to a treasure from the treasures of Paradise?"I said, "Yes, Messenger of Allah."He said, "There is no power and no strength except through Allah, and there is no refuge from Allah except to Him."
قال رسول الله ﷺ: ألا أدلك على كنز من كنوز الجنة؟ قلت: بلى يا رسول الله، فقال: لا حول ولا قوة إلا بالله، ولا ملجأ من الله إلا إليه.
Ahmad (8085), Bazzar - Kashf Astar (3089), and Nasai in Amal al-Yawm wal-Layla (358) all narrated it, and Hakim graded it sahih (1/517), all of them through routes from Abu Ishaq, from Kumayl bin Ziyad, from Abu Hurairah, who related it in a long hadith. Kumayl bin Ziyad is Ibn Nuhayk Hanafi, reliable in his hadith but suspect in his religion, as he was an extremist in his Shiism. The hadith has also been narrated through other routes from Abu Hurairah, some of which are defective, as noted in Tarikh al-Kabir (1/100) and Ilal Ibn Abu Hatim (2000).
