Musannaf Ibn Abi Shaybah 3928 — Praying in camel pens

Asim bin al-Mundhir said: Sayyiduna Ibn al-Zubayr (may Allah be pleased with him) went to Muzdalifah at a time other than the months of Hajj, and there he led us in prayer in a sheepfold, even though there were other places where he could have led us in prayer. My view is that he wanted to show us that praying in such a place is permissible.
