A slave girl belonging to Kaʿb used to graze some sheep at Sl'a (mountain). Once one of her sheep was dying. She reached it (before it died) and slaughtered it with a stone. The Prophet ﷺ was asked, and he said, "Eat it." (Using translation from Bukhārī 5505)
أَخْبَرَهُ أَنَّ جَارِيَةً لِكَعْبِ بْنِ مَالِكٍ ؓ كَانَتْ تَرْعَى غَنَمًا لَهُ بِالسَّلْعِ فَأُصِيبَتْ شَاةٌ مِنْهَا فَأَدْرَكَتْهَا فَذَبَحَتْهَا بِحَجَرٍ فَسُئِلَ رَسُولُ اللهِ ﷺ عَنْ ذَلِكَ فَقَالَ لَا بَأْسَ بِهَا فَكُلُوهَا
