Musnad Ahmad 30:1194

Rawh and Abu al-Mundhir narrated to us, they said: Malik narrated to us, from Ishaq ibn Abdullah ibn Abi Talhah, from Zafar ibn Sa'sa'ah ibn Malik, from his father, from Abu Hurairah, that the Messenger of Allah, peace and blessings of Allah be upon him, used to say when he finished the morning prayer: "Has any one of you seen a vision tonight? For there does not remain after me of prophethood except the righteous vision."
