حَدَّثَنَا سَعِيدُ بْنُ عُفَيْرٍ، حَدَّثَنَا ابْنُ وَهْبٍ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي أَبُو سَلَمَةَ، قَالَ أَخْبَرَنِي جَابِرُ بْنُ عَبْدِ اللَّهِ، قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم بِمَرِّ الظَّهْرَانِ نَجْنِي الْكَبَاثَ فَقَالَ ‏"‏عَلَيْكُمْ بِالأَسْوَدِ مِنْهُ، فَإِنَّهُ أَيْطَبُ ‏"‏‏.‏ فَقَالَ أَكُنْتَ تَرْعَى الْغَنَمَ قَالَ ‏"‏ نَعَمْ، وَهَلْ مِنْ نَبِيٍّ إِلاَّ رَعَاهَا ‏"
Translation
Narrated Jabir bin `Abdullah

We were with Allah's Messenger (ﷺ) collecting Al-Kabath at Mar-Az-Zahran. The Prophet (ﷺ) said, "Collect the black ones, for they are better." Somebody said, (O Allah's Messenger (ﷺ)!) Have you ever shepherded sheep?" He said, "There has been no prophet but has shepherded them. "
