The growth of trees on graves has no connection to righteousness or corruption

I observe, O Shaykh, that some of the common people, when they see trees growing on a grave, describe the owner of the grave as having such and such qualities. Is there any connection between the growth of trees on graves and punishment?
Answer: This has no basis; there is no foundation for this, and the plants have no significance. When the rains fall, the soil on the grave may be suitable soil, arable soil, in which trees and grass grow. This does not indicate righteousness or corruption; rather, it is one of the natural causes of the land, in which Allah has placed the roots and seeds of plants.
So if the land contains seeds, they grow by the permission of Allah, and if it is empty, nothing grows on it.
The conclusion is that it grows on the grave of the righteous and on the grave of the wicked. It is not evidence that he is righteous; rather, this is from the conjectures of the common people or from the people of deviant beliefs and paths.
