Jami` at-Tirmidhi, Book 49, Hadith 4059 (In-Book)

Narrated Abu Hurairah: that the Prophet said: "While a man was tending some of his sheep, a wolf came and took a sheep. So its owner came and retrieved it. The wolf said: 'What will you do for it on the Day of the Predator, the day when there will be no shepherd for it other than me?'" The Messenger of Allah said: "So I believe in that, I and Abu Bakr, and 'Umar." (One of the narrators) Abu Salamah said: "And the two of them were (present) not among the people that day."

حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا أَبُو دَاوُدَ الطَّيَالِسِيُّ، عَنْ شُعْبَةَ، عَنْ سَعْدِ بْنِ إِبْرَاهِيمَ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ بَيْنَمَا رَجُلٌ يَرْعَى غَنَمًا لَهُ إِذْ جَاءَ ذِئْبٌ فَأَخَذَ شَاةً فَجَاءَ صَاحِبُهَا فَانْتَزَعَهَا مِنْهُ فَقَالَ الذِّئْبُ كَيْفَ تَصْنَعُ بِهَا يَوْمَ السَّبُعِ يَوْمَ لاَ رَاعِيَ لَهَا غَيْرِي ‏"‏ ‏.‏ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ فَآمَنْتُ بِذَلِكَ أَنَا وَأَبُو بَكْرٍ وَعُمَرُ ‏"‏ ‏.‏ قَالَ أَبُو سَلَمَةَ وَمَا هُمَا فِي الْقَوْمِ يَوْمَئِذٍ ‏.‏
