Sahih Bukhari Volume 7, Book 76, Hadith 5783

وَزَادَ اللَّيْثُ قَالَ حَدَّثَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، قَالَ وَسَأَلْتُهُ هَلْ نَتَوَضَّأُ أَوْ نَشْرَبُ أَلْبَانَ الأُتُنِ أَوْ مَرَارَةَ السَّبُعِ أَوْ أَبْوَالَ الإِبِلِ‏.‏ قَالَ قَدْ كَانَ الْمُسْلِمُونَ يَتَدَاوَوْنَ بِهَا، فَلاَ يَرَوْنَ بِذَلِكَ بَأْسًا، فَأَمَّا أَلْبَانُ الأُتُنِ فَقَدْ بَلَغَنَا أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ لُحُومِهَا، وَلَمْ يَبْلُغْنَا عَنْ أَلْبَانِهَا أَمْرٌ وَلاَ نَهْىٌ، وَأَمَّا مَرَارَةُ السَّبُعِ قَالَ ابْنُ شِهَابٍ أَخْبَرَنِي أَبُو إِدْرِيسَ الْخَوْلاَنِيُّ أَنَّ أَبَا ثَعْلَبَةَ الْخُشَنِيَّ أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ أَكْلِ كُلِّ ذِي نَابٍ مِنَ السَّباعِ‏.‏

Al-Laith said: Narrated Yunus: I asked Ibn Shihab, "May we perform the ablution with the milk of she-asses or drink it, or drink the bile of wild animals or urine of camels?" He replied, "The Muslims used to treat themselves with that and did not see any harm in it. As for the milk of she-asses, we have learnt that Allah's Apostle forbade the eating of their meat, but we have not received any information whether drinking of their milk is allowed or forbidden." As for the bile of wild animals, Ibn Shihab said, "Abu Idris Al-Khaulani told me that Allah's Apostle forbade the eating of the flesh of every wild beast having fangs."
