The Prophet ﷺ started ascending a high place or hill. A man (amongst his companions) ascended it and shouted in a loud voice, "La ilaha illal-lahu wallahu Akbar." (At that time) Messenger of Allah ﷺ was riding his mule. Messenger of Allah ﷺ said, "You are not calling upon a deaf or an absent one." and added, "O Abu Musa (or, O ʿAbdullah)! Shall I tell you a sentence from the treasure of Paradise?" I said, "Yes." He said, "La haul a wala quwwata illa billah," (Using translation from Bukhārī 6409)   

أَخَذَ النَّاسُ فِي عُقْبَةٍ أَوْ ثَنِيَّةٍ فَكُلَّمَا عَلَا عَلَيْهَا رَجُلٌ نَادَى بِأَعْلَى صَوْتِهِ لَا إِلَهَ إِلَّا اللهُ وَاللهُ أَكْبَرُ فَقَالَ رَسُولُ اللهِ ﷺ «إِنَّكُمْ لَا تَدْعُونَ أَصَمَّ وَلَا غَائِبًا» ثُمَّ قَالَ يَا أَبَا مُوسَى «أَلَا أَدُلُّكَ عَلَى كَنْزٍ مِنْ كُنُوزِ الْجَنَّةِ» قُلْتُ بَلَى قَالَ تَقُولُ «لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللهِ»
