Hadith 509370
Chapter 20: Hajj - كتاب الحج
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ أَبِي الزُّبَيْرِ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، قَضَى فِي الضَّبُعِ بِكَبْشٍ وَفِي الْغَزَالِ بِعَنْزٍ وَفِي الأَرْنَبِ بِعَنَاقٍ وَفِي الْيَرْبُوعِ بِجَفْرَةٍ .
Yahya related to me from Malik from Abu'z-Zubayr that Umar ibn al-Khattab gave the judgement of a ram for a hyena, a female goat for a gazelle, a she-goat less than one year old for a rabbit, and a four month old kid for a jerboa.
