We were along with Allah's Apostle ﷺ on a journey when the people began to pronounce "Allahu Akbar" in a loud voice. Thereupon Messenger of Allah ﷺ said: O people, show mercy to yourselves for you are not calling One who is deaf or absent. Verily, you are calling One who is All-Hearing (and) Near to you and is with you. Abu Musa said that he had been behind him (the Prophet) and reciting: "There is neither might nor power but that of Allah." He (the Prophet), while addressing 'Abdullah b. Qais, said: Should I not direct you to a treasure from amongst the treasures of Paradise? I ('Abdullah b. Qais) said: Messenger of Allah, do it, of course. Thereupon he (the Prophet) said: Then recite: "There is no might and no power but that of Allah."
كُنَّا مَعَ النَّبِيِّ ﷺ فِي سَفَرٍ فَجَعَلَ النَّاسُ يَجْهَرُونَ بِالتَّكْبِيرِ فَقَالَ النَّبِيُّ ﷺ أَيُّهَا النَّاسُ ارْبَعُوا عَلَى أَنْفُسِكُمْ إِنَّكُمْ لَيْسَ تَدْعُونَ أَصَمَّ وَلاَ غَائِبًا إِنَّكُمْ تَدْعُونَ سَمِيعًا قَرِيبًا وَهُوَ مَعَكُمْ قَالَ وَأَنَا خَلْفَهُ وَأَنَا أَقُولُ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ فَقَالَ يَا عَبْدَ اللَّهِ بْنَ قَيْسٍ أَلاَ أَدُلُّكَ عَلَى كَنْزٍ مِنْ كُنُوزِ الْجَنَّةِ فَقُلْتُ بَلَى يَا رَسُولَ اللَّهِ قَالَ قُلْ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ
