Narrated Anas: The Prophet said, "A single endeavor (of fighting) in Allah's Cause in the afternoon or in the forenoon is better than all the world and whatever is in it. A place in Paradise as small as the bow or lash of one of you is better than all the world and whatever is in it. And if a houri from Paradise appeared to the people of the earth, she would fill the space between Heaven and the Earth with light and pleasant scent and her head cover is better than the world and whatever is in it."
