Hazrat Qasim says that nothing breaks the prayer; Allah Almighty is closer than everything.

Hazrat Aisha (may Allah be pleased with her) narrates that the Noble Prophet (peace and blessings be upon him) used to be performing prayer at night, and I would be lying between him and the Qiblah in such a way as a corpse is laid.

Hazrat Ibn Abbas (may Allah be pleased with them) says that as much as possible, prevent those passing in front of you; among the things from which it is most necessary to be cautious about passing in front during prayer, dogs are foremost.

Hazrat Sha'bi says that prayer is not invalidated by anything; however, as much as you are able, prevent those passing in front of you.

It is narrated from Hazrat Abu Dharr Ghifari that the Messenger of Allah, peace and blessings be upon him, said: When a person does not have anything in front of him equal to the wood of a camel's saddle, then the passing of a woman, a donkey, and a black dog will break the prayer. The narrator, Hazrat Abdullah bin Samit, says: I asked, O Abu Dharr! What is the difference between a black dog, a red dog, and a yellow dog? He replied: O my nephew! I asked the Messenger of Allah, peace and blessings be upon him, about this, and he said: The black dog is a devil.

2925 - He said: I said: O Abu Dharr, what is the difference between the black dog and the red dog and the yellow dog? He said: O son of my brother, I asked the Messenger of Allah صلی اللہ علیہ وسلم as you have asked me, and he said: "The black dog is a devil." (2).

Hazrat Mujahid says that a black dog is a devil; it breaks the prayer.

It is similarly narrated from Hazrat Mu'adh.

Hazrat Anas (may Allah be pleased with him) narrates that the prayer is invalidated by the passing of a woman, a donkey, and a dog.

The same is narrated from Hazrat Abu Al-Ahwas.
