Musnad Ahmad 308:1

Rawh ibn ‘Ubadah narrated to us, he said: Zakariyya ibn Ishaq informed us, he said: ‘Amr ibn Dinar narrated to us, from Nafi‘ ibn Jubayr ibn Mut‘im, from Abu Shurayh al-Khuza‘i—and he had companionship [with the Prophet]—he said: I heard the Messenger of Allah, may Allah bless him and grant him peace, saying: "Whoever believes in Allah and the Last Day, let him honor his guest. And whoever believes in Allah and the Last Day, let him do good to his neighbor. And whoever believes in Allah and the Last Day, let him speak good or remain silent."
