The structure of a tree has been reflected in the design of the hierarchy of the mosque.
Roots support the growth of a tree, likewise knowledge is the base for the growth of a human being. So the Libraries and Study areas have been placed on the lower floor of the Mosque Complex.
The ablution areas are placed on either side of the prayer hall, like soil.
A tree has several branches and they all support its growth, in the same way all come together to worship and praise Allah. Hence the Prayer halls have been situated on the top most part of the Mosque Complex.
