Lotte tree marks the utmost boundary in the seventh heaven, where the knowledge of the angels ends.

Some have said that it is the date palm and some say that the example of those trees is given whose roots spread in the earth and whose branches reach the sky and whenever you want you can take fruits from it although apparently no such tree exists.

There is a tradition from the Holy Prophet (S) that: I am the tree and Fatima is its branch and due to Ali and Fatima it has the capability of bearing fruits and Hasan and Husain are its fruits and the friends of Ahlul Bayt (a.s.) are its leaves and all its parts are in Paradise.

It is narrated from Imam Sadiq (a.s.) that the Holy Prophet (S) said: I am the base and the root of that tree and Amirul Momineen (a.s.) is its trunk and the Imams from his progeny are its stems, and the knowledge of the Imams are its fruits and the believers are its leaves. Is there anything else in a tree? No, by Allah, said the narrator. The Hazrat said: By Allah when a believer is born a leaf grows from that tree and when a believer dies, a leaf falls off the tree.
