Q: Is it permissible to put a cover or canopy over the Eidgaah?
A: In places where it rains abundantly (such as Bangladesh) this will be allowed since excessive rain will result in the continuous or perpetual abandonment of an important Sunnat. (Imdaadul-Ahkaam 1/364)
Also permissible under all circumstances to build walls around the Eidgah.
