Musannaf Ibn Abi Shaybah 6637 — Praying in fox skins

Amr bin Sa'id said: Once Abu al-Aliyah entered the mosque and led them in prayer, wearing a cap lined with fox skins. When he began the prayer he took the cap off and put it in his sleeve. When he had finished his prayer I said: Why did you take off your cap and put it in your sleeve? He said: I did not like to pray in it, nor did I like to put it down lest it be stolen, so I put it in my sleeve.
