Hadithcore
Sahih Muslim, 2704 f
sahih

Abu Musa, reported. We were along with Allah's Messenger (ﷺ) in an expedition. The rest of the hadith is the same (and there is an addi- tion of these words in that):

" He (the 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."

وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا الثَّقَفِيُّ، حَدَّثَنَا خَالِدٌ الْحَذَّاءُ، عَنْ أَبِي عُثْمَانَ، عَنْ أَبِي مُوسَى، قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم 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 ‏.‏
