Musnad Ahmad — Hadith #45199

Waki` narrated to us, Sufyan narrated to us, on the authority of Salama bin Kuhail, on the authority of Hujjayya, he said: A man asked Ali, may God be pleased with him, about the cow, and he said about Seven, so he said, “Makosoorah Al-Qarn.” He said, “It will not harm you.” Al-Arja’ said. He said, “When you have reached the ritual ritual, then slaughter it.” The Messenger of God, may God bless him and grant him peace, commanded us. May God’s prayers and peace be upon him, we should look forward with the eye and the ear.
