حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا النَّضْرُ بْنُ شُمَيْلٍ، حَدَّثَنَا عُثْمَانُ، - وَهُوَ ابْنُ غِيَاثٍ - حَدَّثَنَا أَبُو عُثْمَانَ، عَنْ أَبِي مُوسَى الأَشْعَرِيِّ، قَالَ قَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم " أَلاَ أَدُلُّكَ عَلَى كَلِمَةٍ مِنْ كُنُوزِ الْجَنَّةِ - أَوْ قَالَ - عَلَى كَنْزٍ مِنْ كُنُوزِ الْجَنَّةِ " . فَقُلْتُ بَلَى . فَقَالَ " لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ " .
Abu Musa Ash'ari reported that Allah's Messenger (ﷺ) said to him: Should I not direct you to the words from the treasures of Paradise, or he said: Like a treasure from the treasures of Paradise? I said: Of course, do that. Thereupon he said:" There is no might and no power but that of Allah."
