The quadrilateral Charbagh concept is based on the four gardens of Paradise mentioned in Chapter (Surah) 55, Ar-Rahman "The Beneficient", in the Qur'an:
"And for him, who fears to stand before his Lord, are two gardens." (Chapter 55: Verse 46)
"And beside them are two other gardens." (Chapter 55: Verse 62)
One of the hallmarks of Charbagh garden is the four-part garden laid out with axial paths that intersect at the garden's centre. This highly structured geometrical scheme, called the chahar bagh, became a powerful method for the organization and domestication of the landscape, itself a symbol of political territory.
