Sunan an-Nasa'i 4402
It was narrated that Abu Sa'eed Al-Khudri said:
"A man form among the Ansar had a she-camel which used to graze in front of Uhud. Something happened to it, and he slaughtered it with a stake,"- (Ayyub, one of the narrators, said) I said to Zaid:' A stake of wood or of iron?" He said "No of wood."- "Then he went to the Prophet and asked him, and he told him to eat it." (Sahih )
أَخْبَرَنِي مُحَمَّدُ بْنُ مَعْمَرٍ، قَالَ حَدَّثَنَا حَبَّانُ بْنُ هِلاَلٍ، قَالَ حَدَّثَنَا جَرِيرُ بْنُ حَازِمٍ، قَالَ حَدَّثَنَا أَيُّوبُ، عَنْ زَيْدِ بْنِ أَسْلَمَ، فَلَقِيتُ زَيْدَ بْنَ أَسْلَمَ فَحَدَّثَنِي عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ كَانَتْ لِرَجُلٍ مِنَ الأَنْصَارِ نَاقَةٌ تَرْعَى فِي قِبَلِ أُحُدٍ فَعُرِضَ لَهَا فَنَحَرَهَا بِوَتَدٍ ‏.‏ فَقُلْتُ لِزَيْدٍ وَتَدٌ مِنْ خَشَبٍ أَوْ حَدِيدٍ قَالَ لاَ بَلْ خَشَبٌ فَأَتَى النَّبِيَّ صلى الله عليه وسلم فَسَأَلَهُ فَأَمَرَهُ بِأَكْلِهَا ‏.‏
