Sunan Abi Dawud, 4783
sahih· Al-Albani

Bakr said:

The Prophet (ﷺ) sent Mu`adh for some of his work. He then transmitted the rest of the tradition mentioned above. Abu Dawud said: This tradition is sounder of the two traditions.

حَدَّثَنَا وَهْبُ بْنُ بَقِيَّةَ، عَنْ خَالِدٍ، عَنْ دَاوُدَ، عَنْ بَكْرٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم بَعَثَ أَبَا ذَرٍّ بِهَذَا الْحَدِيثِ ‏.‏ قَالَ أَبُو دَاوُدَ وَهَذَا أَصَحُّ الْحَدِيثَيْنِ ‏.‏
