Narrated Ata' ibn Yasar:

A man of Banu Harith was pasturing a pregnant she-camel in one of the ravines of Uhud, (he saw that) it was about to die; he could find nothing to slaughter it; he took a stake and stabbed it in the upper part of its breast until he made its blood flow.

He then came to the Prophet ﷺ and informed him about that, and he ordered him to eat it.

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ رَجُلٍ، مِنْ بَنِي حَارِثَةَ أَنَّهُ كَانَ يَرْعَى لِقْحَةً بِشِعْبٍ مِنْ شِعَابِ أُحُدٍ فَأَخَذَهَا الْمَوْتُ فَلَمْ يَجِدْ شَيْئًا يَنْحَرُهَا بِهِ فَأَخَذَ وَتَدًا فَوَجَأَ بِهِ فِي لَبَّتِهَا حَتَّى أُهْرِيقَ دَمُهَا ثُمَّ جَاءَ إِلَى النَّبِيِّ ﷺ فَأَخْبَرَهُ بِذَلِكَ فَأَمَرَهُ بِأَكْلِهَا .
