Musnad Ahmad 32:485

Abu al-Nadr narrated to us, 'Isa ibn Tahman al-Bakri narrated to us, he said: I heard Anas ibn Malik saying: "A man came until he peered into the chamber of the Prophet, may Allah bless him and grant him peace. The Prophet of Allah, may Allah bless him and grant him peace, stood up and took an arrow-head, then he came until he was parallel with the man. He brought him, and the man drew back, and he went away."
