Musannaf Ibn Abi Shayba 37:352

Waki' narrated to us, from Isma'il bin Abi Khalid, from Qays, from al-Mughira bin Shu'ba, who said: "No one used to ask the Messenger of Allah, may Allah bless him and grant him peace, about the Dajjal more than I did. He said: 'And what do you ask me about him?' I said: 'The people say that he has food and drink.' He said: 'He is more insignificant to Allah than that.'"
