صحيح مسلم#2628Sahihوَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا ابْنُ نُمَيْرٍ، وَقَالَ أَبُو بَكْرٍ، حَدَّثَنَا عَبْدُ الرَّحِيمِ بْنُ سُلَيْمَانَ، كِلاَهُمَا عَنْ هِشَامٍ، بِهَذَا الإِسْنَادِ أَنَّ حَمْزَةَ، قَالَ إِنِّي رَجُلٌ أَصُومُ أَفَأَصُومُ فِي السَّفَرِ
This hadith has been narrated on the authority of Hisham with the same chain of transmitters that Hamza said:I am a person much used to fasting. Should I fast during the journey? (The rest of the hadith is the same)
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih Muslim is accepted as Sahih (authentic) by the established status of the book.
