Musannaf Ibn Abi Shayba 27:728

'Abdullah ibn Idris narrated to us, from Muhammad ibn Ishaq, from 'Asim ibn 'Umar, who said: A man came to the Messenger of Allah, may Allah bless him and grant him peace, and began mentioning Quraysh and what they had gathered, and he began threatening him with them. The Messenger of Allah, may Allah bless him and grant him peace, said to him: "The Banu Qayla will refuse that for you; they are a people who have excess in their sharpness."
