2 down the middle of the great street of the city. On each side of the river stood the tree of life, bearing twelve crops of fruit, yielding its fruit every month. And the leaves of the tree are for the healing of the nations.
This sounds very similar to a verse in the holy Quran:
Do you not see how Allah compares a good word to a good tree? Its root is firm and its branches reach the sky, yielding its fruit in every season by the Will of its Lord. This is how Allah sets forth parables for the people, so perhaps they will be mindful.
{Ibrahim:24-25}
And it’s tafseer according to the Ahlul bayt AS:
3- It is narrated to us by Ahmad, from Al Hassan Bin Mahboub, from Momin Al Taq, from Sallam Bin Al Mustaneer who said, ‘I asked Abu Ja’farasws about Words of Allahazwj the Exalted: like a good tree, its roots are stable and its branches are in the sky [14:24] Yielding its fruit in every season by the permission of its Lord? [14:25]. Heasws said: ‘The tree is Rasool-Allahsaww. Hesaww installed it firmly in the Clan of Hashimas, and the root of the tree is (Syeda) Fatimaasws, and the trunk of the tree is Aliasws Amir Al Momineenasws, and branches of the tree and its fruits are the Imams^asws, and leaves of the tree are the Shias, and that the new-born is born, so a leaf sprouts, and the man from the Shias dies, so a leaf falls off’.
