Musnad Ahmad 1302:8

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from Sulayman, from Dhakwan, from 'Ata' ibn Yasar, from a sheikh, from Abu al-Darda', that he asked the Messenger of Allah, peace and blessings of Allah be upon him, about this verse: "Those who believed and used to fear Allah, for them are glad tidings in the life of this world" [Yunus: 64]. He said: "It is the righteous vision that the Muslim sees, or that is seen for him."
