28 The Ability to Change One’s Form as Desired: - (Jannah: The Garden from the Qur'an and Hadith) -

If people were offered the opportunity to choose their facial features
and physical characteristics, there is no doubt that most would choose
to look flawlessly beautiful. This is because human beings take
delight in beauty and always look for perfection. We notice the
slightest flaw, but the beauty we seek cannot be found in this world.
Even if a person were the most beautiful individual in the world,
distress, illness and, most importantly, mortality casts a shadow over
this beauty. It is a part of our test that every thing in this world
has been created with defects and imperfections. There is a good
reason for these: to direct us towards the afterlife and make us yearn
for the Garden, the real place to find the beauty and perfection that
delights us. In the Garden, Allah will recreate people with perfect
beauty and give them the most pleasing forms. And this beauty will not
be limited to one form. Allah will give His slaves in the Garden the
choice of whatever form they desire at any time so that the people of
the Garden can have a variety of beautiful forms whenever they want.
The Prophet tells us that believers can select a form they like from
markets in the Garden and assume it:
There is in the Garden a market wherein there will be no buying and
selling, but forms of men and women. So when a man wishes a form, he
will enter into it. (Narrated by Ali, at-Tirmidhi)
You will see the wrongdoers afraid of what they have earned, when it
is about to land right on top of them, whereas those who believe and
do right actions will be in the lush Meadows of the Gardens. They will
have whatever they wish for with their Lord. That is the great favor.
(Surat ash-Shura: 22)
