Narrated Abu Huraira:

Allah's Apostle ﷺ said, "Whilst a shepherd was amongst his sheep, a wolf attacked them and took away a sheep. The shepherd chased it and got that sheep freed from the wolf. The wolf turned towards the shepherd and said, 'Who will guard the sheep on the day of wild animals when it will have no shepherd except myself?" The people said, "Glorified be Allah." The Prophet ﷺ said, "But I believe in it and so do Abu Bakr and 'Umar although Abu Bakr and 'Umar were not present there (at the place of the event).

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، حَدَّثَنَا اللَّيْثُ، حَدَّثَنَا عُقَيْلٌ، عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، وَأَبِي، سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ قَالاَ سَمِعْنَا أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ " بَيْنَمَا رَاعٍ فِي غَنَمِهِ عَدَا الذِّئْبُ فَأَخَذَ مِنْهَا شَاةً، فَطَلَبَهَا حَتَّى اسْتَنْقَذَهَا، فَالْتَفَتَ إِلَيْهِ الذِّئْبُ فَقَالَ لَهُ مَنْ لَهَا يَوْمَ السَّبُعِ، لَيْسَ لَهَا رَاعٍ غَيْرِي". فَقَالَ النَّاسُ سُبْحَانَ اللَّهِ. فَقَالَ النَّبِيُّ ﷺ " فَإِنِّي أُومِنُ بِهِ وَأَبُو بَكْرٍ وَعُمَرُ " وَمَا ثَمَّ أَبُو بَكْرٍ وَعُمَرُ.
