Al-Adab Al-Mufrad, Book 38, Hadith 902 (English) ⓘ

Abu Hurayra said, "I heard the Prophet, may Allah bless him and grant him peace, say, 'While a shepherd was tending to his sheep, a wolf came and snatched one of the sheep. The shepherd went after the wolf which turned to him and said, 'Who will look after them on the 'Day of Wild Beasts'? They will have no shepherd but me.' People said, 'Glory be to Allah!' The Messenger of Allah, may Allah bless him and grant him peace, said, 'I believe it - I, Abu Bakr and 'Umar.'"

حَدَّثَنَا يَحْيَى بْنُ صَالِحٍ الْمِصْرِيُّ، عَنْ إِسْحَاقَ بْنِ يَحْيَى الْكَلْبِيِّ، قَالَ‏:‏ حَدَّثَنَا الزُّهْرِيُّ، قَالَ‏:‏ أَخْبَرَنَا أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ، أَنَّ أَبَا هُرَيْرَةَ قَالَ‏:‏ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ‏:‏ بَيْنَمَا رَاعٍ فِي غَنَمِهِ، عَدَا عَلَيْهِ الذِّئْبُ فَأَخَذَ مِنْهُ شَاةً، فَطَلَبَهُ الرَّاعِي، فَالْتَفَتَ إِلَيْهِ الذِّئْبُ فَقَالَ‏:‏ مَنْ لَهَا يَوْمَ السَّبُعِ‏؟‏ لَيْسَ لَهَا رَاعٍ غَيْرِي، فَقَالَ النَّاسُ‏:‏ سُبْحَانَ اللهِ، فَقَالَ رَسُولُ اللهِ صلى الله عليه وسلم‏:‏ فَإِنِّي أُؤْمِنُ بِذَلِكَ، أَنَا وَأَبُو بَكْرٍ وَعُمَرُ‏.‏
