Narrated ‘Abdullah bin Zaid Al-Mazini:
Allah’s Apostle said, “Between my house and the pulpit there is a garden of the gardens of Paradise.”
Narrated Abu Huraira:
The Prophet said, “Between my house and my pulpit there is a garden of the gardens of Paradise, and my pulpit is on my fountain tank (i.e. Al-Kauthar).”
So there is a little bit of heaven on Earth. :D
Knowing that a certain piece of land in Madinah is a garden from the gardens of Paradise is not enough. What we really need to know is what we’re supposed to do when (and if) we visit it. Should we go all desi and start kissing the floor and not make space for anybody to pray there? (Personal experience during last `Umrah.)
Ibn `Uthaymeen said when asked about it:
It is better for him to pray in al-Rawdah which is the area between the minbar of the Prophet (peace and blessings of Allaah be upon him) and the room in which is his grave, because this area is one of the gardens (riyaadh, sing. rawdah) of Paradise.
