Musannaf Ibn Abi Shaybah 39109 — Praying witr on a mount: Abu Hanifah

It is narrated from al-Jurayri that a cat put its mouth into Abu al-Ala's pure water, and he then performed ablution with what the cat had left. And it is mentioned that the view of (Imam) Abu Hanifah is: he considered what a cat has left to be disliked (makruh).
