Garment that was ripped from Adam and Eve

A) It is known that Iblis was banned from Heaven because of his refusal to prostrate to Adam pbuh. So how was he able to enter Heaven, and whisper to Adam, and make him eat of the forbidden tree? The words of Iblis to Adam indicate that he was with him in Heaven, because he pointed to the tree using the pronoun “this” which indicates he was not far from it.

B) What is the tree that Adam pbuh ate from?

C) Was the nakedness of Adam and Eve showing without clothing and then when they ate from the tree they became aware of their nakedness so they covered themselves with the leaves of Heaven? And what are the leaves they covered themselves with?

So they – for example – loves ownership of the land, gold, silver, transplantation, animals, to spend, and fulfilling their desire with the opposite sex.
