Musnad Ahmad 30:926

Abu Qatan narrated to us, Yunus bin ‘Amr bin ‘Abdullah—meaning Ibn Abi Ishaq—narrated to us, from Mujahid, from Abu Hurairah, who said: The Messenger of Allah (ﷺ) said: "Gabriel came to me and said: 'I came to you last night, and nothing prevented me from entering the house you were in except that there was a statue of a man in the house, and there was a curtain with figures on it in the house. So, order that the head of the statue which is at the door of the house be cut off, so it becomes like the shape of a tree. And order that the curtain be cut and made into two cushions to be thrown and stepped upon. And order that the dog be taken out.'" The Messenger of Allah (ﷺ) did so, and it turned out the dog was a puppy belonging to Al-Hasan and Al-Husain that was under a piece of furniture of theirs.
