She has become flabby because of losing weight; can she have surgery to lift her breasts?

We have previously explained
several times on our site that some kinds of cosmetic surgery
are permissible, namely that which is done to treat a fault,
remove a deformity and so on, and some kinds are haraam and
are not allowed, namely that which is done solely for the
purpose of beautification. 

Please see the answer to
questions no. 47694 and
108860. 

So long as the surgery that you
are going to do is to remove a fault that resulted from
losing weight, there is nothing wrong with that if it will
not result in harm that is greater than the harm occurring
right now. 

The scholars of the Standing
Committee for Issuing Fatwas were asked:

One of my friends got married by
the help of Allah. He came to me and said: e came to me and
said that his wife wants to have cosmetic surgery on her face
and breasts, because her nose is large and wide, and she
wants to reduce it by means of the easy methods that modern
science has developed. Is there any doubt about this surgery
or is there any sin involved? Please note that not doing it
may lead to psychological distress because this fault appears
so prominently on her face. 

They replied: If the situation
is as described, and there is the hope that the surgery will
be successful and will not lead to a greater or equal harm,
then it is permissible to do it in order to achieve the
desired purpose, otherwise it is not
permissible. 

Fataawa al-Lajnah
al-Daa’imah,
25/59-60 

Shaykh Ibn Baaz (may Allah have
mercy on him) was asked: 

What is the Islamic ruling on
having surgery to remove physical defects that may occur in
people whether as a result of sickness or an accident, or
that had been present since birth, such as removing extra
digits and repairing the hand to make it look natural, or
removing extra teeth and straightening the rest of the teeth
so that the mouth will go back to normal, or correcting a
harelip and making it look normal, or removing scars caused
by burning, straightening a crooked nose or reducing its size
in order to facilitate breathing, or completing a defective
ear, or tightening drooping eyelids because they block one’s
vision, or tightening sagging skin on the face so that the
face will look more natural, or breast reduction for women in
cases where large breasts are causing spinal problems because
of their weight, or tummy tucks in the case of a sagging
belly and weak abdominal muscles which lead to hernias,
straightening the urethra in males in cases where urine is
contaminating the clothing, removing deformed spots from the
face, and removal of fat in obese individuals which may cause
many diseases such as diabetes, high blood pressure and high
cholesterol levels. Please note that these operations will
not cause any deformity, in sha Allah. 

He replied: 

There is nothing wrong with
treating the problems mentioned with remedies that are
prescribed in sharee‘ah or with permissible remedies from
specialist doctors who think it most likely that the
treatment will be successful, because of the general meaning
of the shar‘i evidence which says that it is permissible to
treat diseases and illnesses with acceptable or permissible
remedies. End quote. 

Majmoo‘ Fataawa Ibn
Baaz,
9/419-420 

Shaykh Ibn ‘Uthaymeen (may Allah
have mercy on him) was asked: 

What is the ruling on cosmetic
surgery that is done by women? 

He replied:

If it is done to remove a fault,
there is nothing wrong with it so long as it does not cause
any harm, because ‘Arfajah (may Allah be pleased with him)
wore a nose made of gold when his nose was cut off. One
example is tightening or lifting drooping breasts. End
quote.
