• Ishaq was asked—another time—about praying in squirrel [skin]. He disliked it.
• I heard Ishaq—another time—say: "As for the skins of beasts of prey, the prohibition from the Prophet (peace and blessings of Allah be upon him) regarding them is authentic, and the Caliphs adhered to it. However, if a person wears it to keep warm, or makes a quilt or something similar out of it, we hope that it is permissible, due to what was mentioned about 'Ammar ibn Yasir and a group of the Followers (Tabi'un) regarding the concession for warming oneself:
1205 - 'Isa ibn Yunus informed us, from 'Adi ibn al-Haytham, he said: Sa'id al-Ta'i narrated to me, from Mutarrif ibn 'Abd Allah, he said: "We entered upon 'Ammar ibn Yasir, and he had a tailor sewing him a garment over a fox-skin qaba' (outer garment)."
• I heard Ishaq say: "As for praying in them, there is no good in that, and if one prays in them, he must repeat the prayer, because the Prophet (peace and blessings of Allah be upon him) only prohibited wearing them due to the impurity, as their meat is not eaten and their skins are not tanned."
(1) This is as it appears in the original; perhaps the word "skins" (julud) was omitted or implied, or something with a similar meaning. (2) This is as it appears in the original; perhaps the correct form is "'Adi Abu al-Haytham". (3) This is as it appears in the original, though the more well-known version is "al-Tahi". See: al-Tarikh al-Kabir (7/44), al-Jarh wa al-Ta'dil (7/3), and Tarikh Dimashq (40/133-136).
