Musnad Ahmad 962:90

Qutaybah narrated to us, Layth narrated to us, from Sa'id ibn Abi Hilal, from 'Ali ibn Khalid, that Abu Umamah al-Bahili passed by Khalid ibn Yazid ibn Mu'awiyah and asked him about the softest word he heard from the Messenger of Allah, may Allah bless him and grant him peace. He said: I heard the Messenger of Allah, may Allah bless him and grant him peace, say: "Verily, all of you will enter Paradise, except for the one who flees from Allah as a camel flees from its owners."
