Musnad Ahmad 1252:2

Yazid ibn Harun narrated to us, he said: Yahya ibn Sa'id al-Ansari informed us that 'Umar ibn Kathir ibn Aflah informed him that he heard 'Ubayd Sanut narrating that he heard Khawlah bint Qays—and he said: The Ansari woman who was with Hamzah ibn 'Abd al-Muttalib—narrating that the Messenger of Allah (peace and blessings of Allah be upon him) entered upon Hamzah in his house, and they discussed the worldly life. The Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, the worldly life is green and sweet. Whoever takes it by its right, it is blessed for him therein. And how many a person who indulges in the wealth of Allah and the wealth of His Messenger will have the Fire on the day he meets Allah."
