The area between the sacred chamber and the Pulpit (Mimbar) is known as the Riadhul Jannah i.e. Garden of Paradise. It is presently distinguished by a green carpet and is also referred to as Rawdah.

Abu Hurairah (may Allah be pleased with him) narrated that the Prophet (peace and blessings of Allah be on him) said:
"Between my house and my pulpit lays a garden from the gardens of Paradise, and my pulpit is upon my fountain (Al-Kauthar)." [Bukhari]
Scholars have interpreted the above narration as follows: The Garden is parallel to a garden above it in Paradise. Or it is in reality a garden of paradise, which will be returned to paradise in the hereafter. Or it is like the gardens of paradise, because the peace and tranquility which is experienced in it when engaged in the remembrance of Allah resembles that of paradise. [Akhbar Madina tur Rasool, Ibn Najjar]
The original size Is approximately 22 meters in length and 15 meters in width, part of it is in the chamber of the Prophet (peace and blessings of Allah be on him).
