Sunan Abi Dawud, Hadith 1521 ⓘ

Narrated AbuMusa al-Ash'ari: Once we accompanied the Messenger of Allah on a journey. When we reached near Medina, the people began to say aloud: "Allah is most great," and they raised their voice. The Messenger of Allah said: O people, you are not supplicating one who is deaf and absent, but you are supplicating One Who is nearer to you than the neck of your riding beast. The Messenger of Allah then said: AbuMusa, should I not point out to you one of the treasures of Paradise? I asked: What is that? He replied: "There is no might and there is no power except in Allah"

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ ثَابِتٍ، وَعَلِيِّ بْنِ زَيْدٍ، وَسَعِيدٍ الْجُرَيْرِيِّ، عَنْ أَبِي عُثْمَانَ النَّهْدِيِّ، أَنَّ أَبَا مُوسَى الأَشْعَرِيَّ، قَالَ كُنْتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي سَفَرٍ فَلَمَّا دَنَوْا مِنَ الْمَدِينَةِ كَبَّرَ النَّاسُ وَرَفَعُوا أَصْوَاتَهُمْ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ يَا أَيُّهَا النَّاسُ إِنَّكُمْ لاَ تَدْعُونَ أَصَمَّ وَلاَ غَائِبًا إِنَّ الَّذِي تَدْعُونَهُ بَيْنَكُمْ وَبَيْنَ أَعْنَاقِ رِكَابِكُمْ ‏"‏ ‏.‏ ثُمَّ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ يَا أَبَا مُوسَى أَلاَ أَدُلُّكَ عَلَى كَنْزٍ مِنْ كُنُوزِ الْجَنَّةِ ‏"‏ ‏.‏ فَقُلْتُ وَمَا هُوَ قَالَ ‏"‏ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ ‏"‏ ‏.‏
