Muwatta Malik, Book 25, Hadith 13 (USC-MSA)

Yahya related to me from Malik from Ibn Shibab from Abu Idris al- Khawlani from Abu Tha~laba al-Khushani that the Messenger of Allah, may Allah bless him and grant him peace, said, "It is haram to eat animals with fangs "

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنِ أَبِي إِدْرِيسَ الْخَوْلاَنِيِّ، عَنْ أَبِي ثَعْلَبَةَ الْخُشَنِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ أَكْلُ كُلِّ ذِي نَابٍ مِنَ السِّبَاعِ حَرَامٌ ‏" ‏ ‏.‏
