Musnad Abu Ya'la al-Mawsili 153:129

And from his father, he said: The Messenger of Allah, peace and blessings of Allah be upon him, said: "There is no envy except in two: A man whom Allah has given the Quran, so he stands with it during the hours of the night and the hours of the day; and a man whom Allah has given wealth, so he spends it during the hours of the night and the hours of the day."
