Ubayd bin al-Walid said: I heard Khawlah bint Qays bin Qahd (may Allah be pleased with her), who was the wife of Hamzah bin Abd al-Muttalib (may Allah be pleased with him), say: I heard the Messenger of Allah (peace and blessings be upon him) say: "This wealth is green and sweet. Whoever acquires it with its right, it is blessed for him; and how many people there are who help themselves to the wealth of Allah and His Messenger as they please; for them is the Fire on the Day of Resurrection."
