Imam al-Shafi'i (may Allah have mercy on him) said: Analogy could allow that the game be eaten even if the dog has eaten from it, and this is the view of Sayyiduna Abdullah bin Umar and Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with them) and some of our companions. We left it only because of the report that al-Sha'bi mentioned, that Sayyiduna Adi bin Hatim (may Allah be pleased with him) heard the Prophet (peace and blessings be upon him) say: "If the dog eats from the game, do not eat the game." When this hadith is established from the Prophet (peace and blessings be upon him), it is not right to abandon it.
