Muwatta Malik, Book 20, Hadith 939 (In-Book)

Yahya related to me from Malik from Hisham ibn Urwa that his father used to say, "For the female of wild animals a cow is given and for the female of gazelles a sheep."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، أَنَّ أَبَاهُ، كَانَ يَقُولُ فِي الْبَقَرَةِ مِنَ الْوَحْشِ بَقَرَةٌ وَفِي الشَّاةِ مِنَ الظِّبَاءِ شَاةٌ ‏.‏
