Jami` at-Tirmidhi Book 47, Hadith 344
“Allah said: ‘I have prepared for My righteous worshippers, what no eye has seen, nor ear has hear, and no human heart has conceived.’ So recite if you wish: No person knows what is kept hidden for them of delights of the eyes as a reward for what they used to do. And in Paradise there is a tree under whose shade a rider can travel for one hundred years without stopping. Recite if you wish: And in shade extended. And the space occupied by a whip in Paradise is better than the world and whatever is in it. Recite if you wish: And whoever is removed away from the Fire and admitted to Paradise, he indeed is successful. The life of this world is only the enjoyment of deception.”
Jabir said: “The Messenger of Allah came out to his Companions, and recited Surat Ar-Rahman from its beginning to its end for them, and they were silent. So he said: ‘I recited it to the Jinns on the ‘Night of the Jinns,’ and they had a better response to it than you did. Each time I came to Allah’s saying: ‘Which of your Lords favor do you deny.’ They said: “We do not deny any of Your favors our Lord! And Yours is praise.”
“Indeed in Paradise there is a tree under whose shade a rider can travel for one hundred years without stopping. Recite if you wish: And in shave extended. And water flowing constantly.”
