What is the basis for it being called the Tree of Immortality?

Question

I have been reading through the different religions and noticed that the tree of immortality is consistent among Chinese mythology and Islam. https://en.wikipedia.org/wiki/Tree_of_life

What is the basis for Islam viewing it as a Tree of Immortality?

Other Abrahamic religions simply call it the Tree of Life.

Answer 1

It was called so by Satan to deceive Adam, his lure was that by eating it he would remain in paradise forever.

فوسوس إليه الشيطان قال يا آدم هل أدلك على شجرة الخلد وملك لا يبلى

Then Satan whispered to him; he said, "O Adam, shall I direct you to the tree of eternity and possession that will not deteriorate?"

^{— Quran 20:120}

وقال ما نهاكما ربكما عن هذه الشجرة إلا أن تكونا ملكين أو تكونا من الخالدين

(Satan) said, "Your Lord did not forbid you this tree except that you become angels or become of the immortal."

^{— Quran 7:20}

It is the same thing, as 'life' there means 'eternal life':

And the Lord God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever

^{— Genesis 3:22}
