Abu Tufail reports: I asked Sayyiduna Ali bin Abi Talib (may Allah be pleased with him): Do you have anything besides the Book of Allah? He replied: No, except for something, a small scroll inside the sheath of the sword. The narrator says: We found in it this statement: "May Allah curse the one who sacrifices an animal in the name of other than Allah, and may Allah curse the one who attributes himself to someone other than his real master."
