Musannaf Ibn Abi Shayba 33:1031

Waki’ narrated to us, from Sufyan, who said: I heard Zayd ibn Aslam saying regarding this verse: "Do not fear and do not grieve." He said: Do not fear what is before you, and do not grieve for what you have left behind. "And receive good tidings of Paradise, which you were promised." He said: The good tidings are at three stations: at the time of death, in the grave, and at the resurrection.
