حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا عَبْدُ الْوَاحِدِ، عَنْ عَاصِمٍ، عَنْ أَبِي عُثْمَانَ، عَنْ أَبِي مُوسَى الأَشْعَرِيِّ ـ رضى الله عنه ـ قَالَ لَمَّا غَزَا رَسُولُ اللَّهِ صلى الله عليه وسلم خَيْبَرَ ـ أَوْ قَالَ لَمَّا تَوَجَّهَ رَسُولُ اللَّهِ صلى الله عليه وسلم ـ أَشْرَفَ النَّاسُ عَلَى وَادٍ، فَرَفَعُوا أَصْوَاتَهُمْ بِالتَّكْبِيرِ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ، لاَ إِلَهَ إِلاَّ اللَّهُ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ ارْبَعُوا عَلَى أَنْفُسِكُمْ، إِنَّكُمْ لاَ تَدْعُونَ أَصَمَّ وَلاَ غَائِبًا، إِنَّكُمْ تَدْعُونَ سَمِيعًا قَرِيبًا وَهْوَ مَعَكُمْ ‏"‏‏.‏ وَأَنَا خَلْفَ دَابَّةِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَسَمِعَنِي وَأَنَا أَقُولُ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ، فَقَالَ لِي ‏"‏ يَا عَبْدَ اللَّهِ بْنَ قَيْسٍ ‏"‏‏.‏ قُلْتُ لَبَّيْكَ رَسُولَ اللَّهِ‏.‏ قَالَ ‏"‏ أَلاَ أَدُلُّكَ عَلَى كَلِمَةٍ مِنْ كَنْزٍ مِنْ كُنُوزِ الْجَنَّةِ ‏"‏‏.‏ قُلْتُ بَلَى يَا رَسُولَ اللَّهِ فِدَاكَ أَبِي وَأُمِّي‏.‏ قَالَ ‏"‏ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ ‏"‏‏.‏
