Explanation & Benefits
Maulana Ataullah Sajid
It is permissible to relieve oneself behind a tree as a screen, provided that the tree is not a fruit-bearing one. The fruit of the date palm is harvested in a specific season; therefore, in other seasons, there is no need for people to approach it to obtain its fruit. The shade of a date grove is indeed utilized for benefit. Individually planted trees are not generally considered important for this purpose; however, small trees that have not yet reached fruit-bearing age provide a good screen.
