Never has Allah or His messengers (angels) ever broken their promise. Then he cast a glance (and by chance) found a puppy under his cot and said: 'A'isha, when did this dog enter here? She said: By Allah, I don't know He then commanded and it was turned out. Then Gabriel came and Allah's Messenger (ﷺ) said to him: You promised me and I waited for you, but you did not come, whereupon he said: It was the dog in your house which prevented me (to come), for we (angels) do not enter a house in which there is a dog or a picture.

Allah's Messenger, I find a change in your mood today. Allah's Messenger (ﷺ) said: Gabriel had promised me that he would meet me tonight, but he did not meet me. By Allah, he never broke his promises, and Allah's Messenger (ﷺ) spent the day in this sad (mood). Then it occurred to him that there had been a puppy under their cot. He commanded and it was turned out. He then took some water in his hand and sprinkled it at that place. When it was evening Gabriel met him and he said to him: you promised me that you would meet me the previous night. He said: Yes, but we do not enter a house in which there is a dog or a picture. Then on that very morning he commanded the killing of the dogs until he announced that the dog kept for the orchards should also be killed, but he spared the dog meant for the protection of extensive fields (or big gardens).

Angels do not enter a house in which there is a dog or a picture.

I heard Allah's Messenger (ﷺ) as saying: Angels do not enter the house in which there is a dog or a statue.
