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  

This hadith has been narrated on the authority of 'Asim with the same chain of transmitters.  

عَنْ عَاصِمٍ بِهَذَا الإِسْنَادِ نَحْوَهُ  

" There is no god but Allah, Allah is the Greatest." Thereupon Allah's Apostle ﷺ said: Verily, you are not supplicating One Who is deaf or absent. He said: Abu Musa or Abdullah b Qais, should I not direct you to the words (which form) the treasure of Paradise? I said: Messenger of Allah, what are these? He said:" There is no might and no power but that of Allah."  

عَنْ أَبِي مُوسَى أَنَّهُمْ كَانُوا مَعَ رَسُولِ اللَّهِ ﷺ وَهُمْ يَصْعَدُونَ فِي ثَنِيَّةٍ قَالَ فَجَعَلَ رَجُلٌ كُلَّمَا عَلاَ ثَنِيَّةً نَادَى لاَ إِلَهَ إِلاَ اللَّهُ وَاللَّهُ أَكْبَرُ قَالَ فَقَالَ نَبِيُّ اللَّهِ ﷺ إِنَّكُمْ لاَ تُنَادُونَ أَصَمَّ وَلاَ غَائِبًا قَالَ فَقَالَ يَا أَبَا مُوسَى أَوْ يَا عَبْدَ اللَّهِ بْنَ قَيْسٍ أَلاَ أَدُلُّكَ عَلَى كَلِمَةٍ مِنْ كَنْزِ الْجَنَّةِ قُلْتُ مَا هِيَ يَا رَسُولَ اللَّهِ قَالَ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ  

This hadith has been transmitted on the authority of Abu Musa with a slight variation of wording.  

بَيْنَمَا رَسُولُ اللَّهِ ﷺ فَذَكَرَ نَحْوَهُ  

We were along with Allah's Apostle ﷺ on a journey; the rest of the hadith is the same as transmitted by A'sim.  

كُنَّا مَعَ النَّبِيِّ ﷺ فِي سَفَرٍ فَذَكَرَ نَحْوَ حَدِيثِ عَاصِمٍ  

" He (the Holy Prophet) said: He Whom you are sup- plicating is nearer to every one of you than the neck of his camel." And there is no mention of these words:" There is no might and no power but that of Allah."  

كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ فِي غَزَاةٍ فَذَكَرَ الْحَدِيثَ وَقَالَ فِيهِ وَالَّذِي تَدْعُونَهُ أَقْرَبُ إِلَى أَحَدِكُمْ مِنْ عُنُقِ رَاحِلَةِ أَحَدِكُمْ وَلَيْسَ فِي حَدِيثِهِ ذِكْرُ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ  

Should I not direct you to the words from the treasures of Paradise, or he said: Like a treasure from the treasures of Paradise? I said: Of course, do that. Thereupon he said:" There is no might and no power but that of Allah."  

لِي رَسُولُ اللَّهِ ﷺ أَلاَ أَدُلُّكَ عَلَى كَلِمَةٍ مِنْ كُنُوزِ الْجَنَّةِ أَوْ قَالَ عَلَى كَنْزٍ مِنْ كُنُوزِ الْجَنَّةِ فَقُلْتُ بَلَى فَقَالَ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ  

Teach me a supplication which I should recite in my prayer. Thereupon he (the Holy Prophet) said: Recite:" O Allah, I have done great wrong to myself." According to Qutaiba (the words were: ) much (wrong) -there is none to forgive the sins but Thou only, say:" Grant me pardon from Thyself, have mercy upon me for Thou art much Forgiving and Compassionate."  

أَنَّهُ قَالَ لِرَسُولِ اللَّهِ ﷺ عَلِّمْنِي دُعَاءً أَدْعُو بِهِ فِي صَلاَتِي قَالَ قُلِ اللَّهُمَّ إِنِّي ظَلَمْتُ نَفْسِي ظُلْمًا كَبِيرًا وَقَالَ قُتَيْبَةُ كَثِيرًا وَلاَ يَغْفِرُ الذُّنُوبَ إِلاَّ أَنْتَ فَاغْفِرْ لِي مَغْفِرَةً مِنْ عِنْدِكَ وَارْحَمْنِي إِنَّكَ أَنْتَ الْغَفُورُ الرَّحِيمُ  

Much wrong (Zulman Kathira).  

لِرَسُولِ اللَّهِ ﷺ عَلِّمْنِي يَا رَسُولَ اللَّهِ دُعَاءً أَدْعُو بِهِ فِي صَلاَتِي وَفِي بَيْتِي ثُمَّ ذَكَرَ بِمِثْلِ حَدِيثِ اللَّيْثِ غَيْرَ أَنَّهُ قَالَ ظُلْمًا كَثِيرًا
