He should fix a staff in the ground, and if he does not have a staff, then he should draw a line. Then, whoever passes in front of him will not harm him."

Musa bin Talha narrates from his father that we used to be performing prayer. Animals would pass in front of us.

Abu Sahba reports: We were present with Sayyiduna Abdullah bin Abbas (may Allah be pleased with them). We discussed the matter of what breaks the prayer. The people said: A donkey and a woman (passing in front of the one praying break the prayer). Then Sayyiduna Abdullah bin Abbas (may Allah be pleased with them) said: I and a young man from Banu Abdul Muttalib came riding a donkey, one in front and one behind. The Prophet Muhammad (peace and blessings be upon him) was leading the people in prayer in an open field at that time. We left the donkey in front of the people, then we came and joined the row. The Prophet Muhammad (peace and blessings be upon him) did not mind this at all.

Awn bin Abu Juhaifah narrates from his father: I was present with the Prophet Muhammad (peace be upon him) at Batha. At that time, you were in a red tent. There were some people with you. Then Sayyiduna Bilal (may Allah be pleased with him) came. He gave the call to prayer (adhan), and while giving the adhan, he turned his face this way and that way. The narrator Sufyan says: That is, he did so while saying «حی علی الصلوۃ» and «حی علی الفلاح» . The narrator says: Then he came out with the leftover water from the ablution of the Prophet Muhammad (peace be upon him), so some people got that water and some did not, until a young boy inserted his hand from under the arms of the people and reached that water. Then Sayyiduna Bilal (may Allah be pleased with him) planted a spear in front of the Prophet Muhammad (peace be upon him) (the Prophet faced it and started performing prayer). Then it was not being forbidden for a donkey, woman, or dog to pass from the other side of it. The Prophet Muhammad (peace be upon him) led two rak‘ahs in the Zuhr prayer, and then continued to perform two rak‘ahs until he arrived in Madinah Munawwarah.

Abdullah bin Samit narrates: I asked Sayyiduna Abu Dharr Ghifari (may Allah be pleased with him) about that which breaks the prayer. He said: If there is nothing in front of you like the back part of a saddle, then a woman, a donkey, and a black dog (passing in front of the praying person) break the prayer. I said: What is special about the black dog, why not a yellow or white one? He said: O my nephew! I asked the Messenger of Allah (peace and blessings be upon him) the same question that you have asked me, so the Messenger of Allah (peace and blessings be upon him) said: "The black dog is a devil." (Imam Ibn Hibban, may Allah have mercy on him, says: "Azramah" is one of the villages of Nasibin.)

He replied: I asked the Prophet (peace and blessings be upon him) the same question that you have asked me, so the Prophet (peace and blessings be upon him) said: The black (dog) is a devil.
