I used to have a mulberry tree that grew on the side of the pathway to my house. Whenever, Sheikh Ibrahim Mia rahmatullah alayhi visited he used to enjoy the mulberries. Sometimes, we used to send mulberries to him as well.
Unfortunately, this tree used to bear so much that the pathway often becomes messed with dropped fruit. We thus cut down the tree. When Sheikh rahmatullah alayhi visited us thereafter, he told us that fruit trees are sadaqah jaariyah (they are means of earning perpertual reward) and we should not cut them down. When we moved to our new home, Sheikh rahmatullah alayhi used to take walks in the garden and identify various plants. If he saw a fruit tree he would remind us about earning sadaqah jaariyah through that tree.
