Musnad Abu Ya'la al-Mawsili 129:55

Wahb narrated to us, Khalid informed us, from Humayd, from Anas: That Thabit ibn Qays gave a speech upon the arrival of the Messenger of Allah (may Allah bless him and grant him peace), and he said: "We protect you with that which we protect ourselves and our children with. So what is for us, O Messenger of Allah?" He said: "For you is Paradise." They said: "We are satisfied."
