Musnad Ahmad 1302:44

Abu Mu'awiyah narrated to us, Al-A'mash narrated to us, from Abu Salih, from 'Ata' ibn Yasar, from a man from the people of Egypt, from Abu al-Darda', who said: He was asked about this verse: "For them are glad tidings in the life of the world and in the Hereafter" [Yunus: 64]? He said: You have asked about something that I have not heard anyone ask about since a man asked the Messenger of Allah, peace and blessings of Allah be upon him, about it. He said: "It is the righteous vision that the Muslim man sees, or is seen for him; his glad tidings in the life of the world, and his glad tidings in the Hereafter is Paradise."
