It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "One who envies envies only on account of two qualities" - or as Allah willed that he (peace and blessings be upon him) should say - "a man to whom Allah has given the Qur'an and he stands with it through the hours of the night and the day, and a man to whom Allah has given wealth and he spends it."
