Sahih al-Bukhari 4081
Narrated Abu Musa:
The Prophet (ﷺ) said, "I saw in a dream that I moved a sword and its blade got broken, and that 
symbolized the casualties which the believers suffered on the day of Uhud. Then I moved it again, and 
it became as perfect as it had been, and that symbolized the Conquest (of Mecca) which Allah helped 
us to achieve, and the union of all the believers. I (also) saw cows in the dream, and what Allah does 
is always beneficial. Those cows appeared to symbolize the faithful believers (who were martyred) on 
the day of Uhud."
حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ بُرَيْدِ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي بُرْدَةَ، عَنْ جَدِّهِ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى ـ رضى الله عنه ـ أُرَى عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏
"‏ رَأَيْتُ فِي رُؤْيَاىَ أَنِّي هَزَزْتُ سَيْفًا فَانْقَطَعَ صَدْرُهُ، فَإِذَا هُوَ مَا أُصِيبَ مِنَ الْمُؤْمِنِينَ يَوْمَ أُحُدٍ، ثُمَّ هَزَزْتُهُ أُخْرَى فَعَادَ أَحْسَنَ مَا كَانَ، فَإِذَا هُوَ مَا جَاءَ بِهِ اللَّهُ مِنَ الْفَتْحِ وَاجْتِمَاعِ الْمُؤْمِنِينَ، وَرَأَيْتُ فِيهَا بَقَرًا وَاللَّهُ خَيْرٌ، فَإِذَا هُمُ الْمُؤْمِنُونَ يَوْمَ أُحُدٍ ‏"‏‏.‏
