حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِى شَيْبَةَ حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ وَأَبُو مُعَاوِيَةَ عَنْ عَاصِمٍ عَنْ أَبِي عُثْمَانَ عَنْ أَبِى مُوسَى قَالَ كُنَّا مَعَ النَّبِىِّ -صلى الله عليه وسلم- فِى سَفَرٍ فَجَعَلَ النَّاسُ يَجْهَرُونَ بِالتَّكْبِيرِ فَقَالَ النَّبِىُّ -صلى الله عليه وسلم- « 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 ».

It was narrated that Abu Musa said: "We were with the Prophet (s.a.w) on a journey, and the people started to recite Takbir (saying: Allahu-Akbar) in loud voices. The Prophet (s.a.w) said: 'O people, be kind to yourselves, for you are not calling upon one who is deaf or absent; you are calling upon One Who is All-Hearing, Ever Near, and He is with you.' I was behind him, and I was saying: 'La hawla wa la quwwata illa billah (There is no power and no strength except with Allah).' He said: 'O 'Abdullah bin Qais, shall I tell you of one of the treasures of Paradise?' I said: 'Yes, O Messenger of Allah.' He said: 'Say: "La hawla wa la quwwata illa billah (There is no power and no strength except with Allah).''
