Isma'il bin Jistas said: Sayyiduna Abdullah bin Amr (may Allah be pleased with him) imposed a fine of forty dirhams for a hunting dog.
Imam al-Bukhari (may Allah have mercy on him) said: No one has corroborated him in this hadith. And the Shaykh said that this is not the position of Sayyiduna Abdullah bin Amr (may Allah be pleased with him); rather, what is authentic from him is different from this.
