Narrated Abu Hurayrah: The Messenger of Allah (ﷺ) said: Gabriel (ﷺ) came to me and said: I came to you last night and was prevented from entering simply because there were images at the door, for there was a decorated curtain with images on it in the house, and there was a dog in the house.
So order the head of the image which is in the house to be cut off (فَمُرْ بِرَأْسِ التِّمْثَالِ الَّذِي فِي الْبَيْتِ يُقْطَعُ) so that it resembles the form of a tree; order the curtain to be cut up and made into two cushions spread out on which people may tread; and order the dog to be turned out.
The Messenger of Allah (ﷺ) then did so. The dog belonged to al-Hasan or al-Husayn and was under their couch. So he ordered it to be turned out.
Abu Dawud said: Al-Nadd means a thing on which clothes are placed like a couch. (Sunan Abi Dawud 4158)
Albani refutes this argument and says: Nothing stopped him from entering except that there were timathil (statues) at the door. In the house there was a qiram satar (thin cloth curtain) that had timathil (images) on it. Pay attention to the words. Jibril said that nothing stopped him from entering except that there were timathil at the door.
