Anas reported God’s messenger as saying, “When you come upon the pastures of paradise feed on them.” On being asked what the pastures of paradise were he replied that they were circles where God is remembered.
‘Abdallah b. Busr told of a desert Arab coming to the Prophet and asking who was best among men, to which he replied, “Happy is he whose life is long and whose deeds are good.” He asked God’s messenger what deed was most excellent, and he replied, “That you should leave the world with the mention of God fresh on your tongue.”
Abu Huraira reported God’s messenger as saying, “If anyone sits in a place where he does not remember God, deprivation will descend on him from God; and if anyone lies down in a place where he does not remember God, vengeance will descend on him from God.”
Abud Darda’ reported God's messenger as saying, “Would you like me to tell you the best and purest of your deeds in the estimation of your King, those which raise your degrees highest, those which are better for you than spending gold and silver, and are better for you than that you should meet your enemy and cut off one another's head?” On receiving a reply in the affirmative he said, “It is remembering God.”
Malik, Ahmad, Tirmidhi and Ibn Majah transmitted it, but Malik traced it no farther back than Abud Darda’.
