Musannaf Ibn Abi Shayba 3:5550

Shababa narrated to us, from Sulayman ibn al-Mughira, from Thabit, from Anas, who said: I arrived from Iraq, and Abu Talha brought dinner, and with him were those whom Allah willed from the companions of the Prophet, may Allah bless him and grant him peace. He said to me, "Come and eat." I said, "Until I pray." He said, "You have adopted the manners of the people of Iraq; come and eat."
