SHAFAQNA – It is narrated from the Prophet of Islam (PBUH) who said: My brother Isa (AS) was passing through a town whilst the fruit trees in that place were pest stricken. People came to him and complained about the problem. Isa (AS) told people: There is a simple way of getting rid of the pests which you are not aware of it. At the time of planting trees, you pour soil first to cover the roots but the first thing which you must do is to pour water on the roots of the tree and then pour soil to protect it from worms. The people of the town started planting trees the correct way and the pests disappeared .
