The Tree in Exchange For a Tree in Paradise
Ibn Abbas has reported that: In the days of the Holy Prophet (S.A.W.), there lived a poor man with a large family. This man could not afford to feed his family but he had a neighbor who had a palm tree in his house that was leaning towards house of the poor man. As a result, the dates, which fell on his side, were sometimes collected and eaten by his children. The neighbor, who was the owner of the palm tree, was a very niggardly and miserly person. Often he would rush to the house of the poor man and snatched the fallen dates from the hands of the children and sometimes even from their mouths.
The poor man came to the Holy Prophet (S.A.W.) and sought his advice. The Messenger of Allah (S.A.W.) called the owner and asked if he could give him the tree in exchange for a tree in Paradise. The owner did not accept the offer.
So a companion, by the name of Abu Huddah rose and said, “Yaa Rasoolallah! If you promise the same for me, I will buy the tree and give it to you”. The Holy Prophet (S.A.W.) agreed. Abu Huddah purchased the tree and presented it to the Messenger of Allah (S.A.W.) who gave it to the poor man.
Hence the following verse was revealed: “As for him who gives and is God wary, and confirms the best promise, We shall surely make smooth the path to bliss for him”. (92:5-7)] (Asbaab al-Nuzool)
