Musnad Ahmad 1012:23

'Affan narrated to us, Aban narrated to us, Yahya narrated to me, from Abu Salamah, from 'Ubadah ibn al-Samit, that he asked the Messenger of Allah (peace and blessings of Allah be upon him) and said: "O Messenger of Allah, what is your opinion regarding the saying of Allah, Blessed and Exalted is He: 'For them are glad tidings in the life of the world and in the Hereafter' [Yunus: 64]?" He said: "You have asked me about something that no one from my nation has asked me about, or anyone before you." He said: "That is the righteous vision that the righteous man sees or is seen for him."
