Sahih al-Bukhari 2484
Narrated Salama:
Once (on a journey) our provisions diminished and the people were reduced to poverty. They went to the Prophet (ﷺ) 
and asked his permission to slaughter their camels, and he agreed. `Umar met them and they told him 
about it, and he said, "How would you survive after slaughtering your camels?" Then he went to the 
Prophet and said, "O Allah's Messenger (ﷺ)! How would they survive after slaughtering their camels?" 
Allah's Messenger (ﷺ) ordered `Umar, "Call upon the people to bring what has remained of their food." A 
leather sheet was spread and all the food was collected and heaped over it. Allah's Messenger (ﷺ) 
stood up and invoked Allah to bless it, and then directed all the people to come with their utensils, and 
they started taking from it till all of them got what was sufficient for them. Allah's Messenger (ﷺ) then said, 
"I testify that None has the right to be worshipped but Allah, and I am His Messenger."
حَدَّثَنَا بِشْرُ بْنُ مَرْحُومٍ، حَدَّثَنَا حَاتِمُ بْنُ إِسْمَاعِيلَ، عَنْ يَزِيدَ بْنِ أَبِي عُبَيْدٍ، عَنْ سَلَمَةَ ـ رضى الله عنه ـ قَالَ خَفَّتْ أَزْوَادُ الْقَوْمِ وَأَمْلَقُوا، فَأَتَوُا النَّبِيَّ صلى الله عليه وسلم فِي نَحْرِ إِبِلِهِمْ فَأَذِنَ لَهُمْ، فَلَقِيَهُمْ عُمَرُ فَأَخْبَرُوهُ فَقَالَ مَا بَقَاؤُكُمْ بَعْدَ إِبِلِكُمْ، فَدَخَلَ عَلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَ يَا رَسُولَ اللَّهِ مَا بَقَاؤُهُمْ بَعْدَ إِبِلِهِمْ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ نَادِ فِي النَّاسِ فَيَأْتُونَ بِفَضْلِ أَزْوَادِهِمْ ‏"‏‏.‏ فَبُسِطَ لِذَلِكَ نِطَعٌ، وَجَعَلُوهُ عَلَى النِّطَعِ‏.‏ فَقَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَدَعَا وَبَرَّكَ عَلَيْهِ ثُمَّ دَعَاهُمْ بِأَوْعِيَتِهِمْ فَاحْتَثَى النَّاسُ حَتَّى فَرَغُوا، ثُمَّ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنِّي رَسُولُ اللَّهِ ‏"‏‏.‏
