Musnad Ahmad 32:541

Hassan narrated to us, Hammad ibn Salamah narrated to us, from Thabit, from Anas, that a man said: "O Messenger of Allah, so-and-so has a date palm tree, and I am building my wall around it. So order him to give it to me so that I may build my wall around it." The Prophet, peace and blessings of Allah be upon him, said to him: "Give it to him in exchange for a date palm tree in Paradise." But he refused. Then Abu al-Dahdah came to him and said: "Sell me your date palm tree for my garden." He did so. Then he came to the Prophet, peace and blessings of Allah be upon him, and said: "O Messenger of Allah, I have bought the date palm tree for my garden." He said: "Then give it to him, for I have given it to you." The Messenger of Allah, peace and blessings of Allah be upon him, said: "How many heavy, fruit-laden clusters of dates does Abu al-Dahdah have in Paradise!" He said it repeatedly. He said: So he went to his wife and said: "O Umm al-Dahdah, get out of the garden, for I have sold it for a date palm tree in Paradise." She said: "A profitable sale," or a word similar to that.
