Yahya related to me from Malik from Yahya ibn Said that Abdullah
ibn Ayyash ibn Abi Rabia al-Makhzumi ordered one of his slaves to
slaughter an animal. When he wanted to slaughter it, he said to him,
"Mention Allah's name." The slave said to him, "I have mentioned the
name!" He said to him, "Mention the name of Allah, bother you!" He
said to him, "I have mentioned the name of Allah " Abdullah ibn Ayyash
said, "By Allah, I shall never eat it!"
