Musannaf Ibn Abi Shaybah 39105 — Praying witr on a mount: Abu Hanifah

It is narrated from Kabshah bint Ka'b, who was married to one of the sons of Abu Qatadah, that she poured out water for Sayyiduna Abu Qatadah (may Allah be pleased with him) to perform ablution. A cat came and began to drink the water, so Abu Qatadah tilted the vessel for it. I began to look on, and he said: "O my niece, are you surprised? The Messenger of Allah (peace and blessings be upon him) said: 'The cat is not impure, for it is among those males or females who frequently come and go among you.'"
