It is narrated from Sayyidah Khawlah bint Qays (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) came to Hamzah (may Allah be pleased with him) - and Khawlah was the wife of Hamzah - and they talked about the world. The Prophet (peace and blessings be upon him) said: "The world is sweet and green. Whoever acquires it with its right, may Allah put blessing in it; and how many people there are who help themselves to the wealth of Allah and His Messenger; for them is the Fire on the Day of Resurrection."
