Sa’ib bin Yazid heard from Sufyan bin Abi Zuhair, who was narrating hadith to the people at the door of the mosque, saying: I heard the Messenger of Allah (peace be upon him) say: Whoever keeps a dog that is neither for farming nor for livestock, then a qirat from his good deeds is reduced every day. Sa’ib said: I asked, did you hear this from the Messenger of Allah (peace be upon him)? He replied: Yes, yes, by the Lord of this mosque, (I heard this from the Prophet, peace be upon him).
