Mixing of Dead Animals with Slaughtered Clean

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from abu al-Mighra’ from al-Halabiy who has said the following: “I once heard abu ‘Abd Allah عليه السلام, saying, ‘If clean (properly slaughtered) become mixed with the dead ones, one can sell them to one who considers dead animals as lawful and use the payment that one receives.’”
