Narrator:Abu Mūsa al-Ash‘ari
حَدَّثَنَا أَبُو كَامِلٍ، فُضَيْلُ بْنُ حُسَيْنٍ حَدَّثَنَا يَزِيدُ، - يَعْنِي ابْنَ زُرَيْعٍ - حَدَّثَنَا التَّيْمِيُّ، عَنْ أَبِي عُثْمَانَ، عَنْ أَبِي مُوسَى، أَنَّهُمْ كَانُوا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُمْ يَصْعَدُونَ فِي ثَنِيَّةٍ - قَالَ - فَجَعَلَ رَجُلٌ كُلَّمَا عَلاَ ثَنِيَّةً نَادَى لاَ إِلَهَ إِلاَ اللَّهُ وَاللَّهُ أَكْبَرُ - قَالَ - فَقَالَ نَبِيُّ اللَّهِ صلى الله عليه وسلم "
إِنَّكُمْ لاَ تُنَادُونَ أَصَمَّ وَلاَ غَائِبًا " . قَالَ فَقَالَ " يَا أَبَا مُوسَى - أَوْ يَا عَبْدَ اللَّهِ بْنَ قَيْسٍ - أَلاَ أَدُلُّكَ عَلَى كَلِمَةٍ مِنْ كَنْزِ الْجَنَّةِ " . قُلْتُ مَا هِيَ يَا رَسُولَ اللَّهِ قَالَ " لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ "
Abu Musa reported that he (and his other companions) were climbing upon the hillock along with Allah's Messenger (ﷺ) and when any person climbed up, he pronounced (loudly):
" There is no god but Allah, Allah is the Greatest." Thereupon Allah's Apostle (ﷺ) said: Verily, you are not supplicating One Who is deaf or absent. He said: Abu Musa or Abdullah b Qais, should I not direct you to the words (which are from) the treasures of Paradise? I said: Allah's Messenger, what are these? He said:" There is no might and no power but that of Allah."
