What is the ruling on cosmetic procedures or organ transplantation for men?

Question : This questioner from Jordan says in this question: regarding cosmetic procedures for men, for example, shortening the nose or transplanting an organ, what is the ruling of the Shari'ah in your view regarding this act?

Answer : As for the aspect of beautification, it is not permissible for a person to alter Allah's creation for the sake of beauty, because this is exactly like the loose women who file their teeth to beautify them. The Prophet (peace and blessings be upon him) cursed the one who files her teeth and the one who has them filed. However, if it is to remove a defect, such as a crooked nose, it is permissible to undergo a procedure to straighten it. Similarly, for overlapping teeth where some are on top of others, it is permissible to undergo a procedure to extract the overlapping tooth or adjust it, and the like of that, such as removing a squint in the eye. This is permissible and there is no harm in it. The evidence for this is that some of the Companions was injured in his nose in one of the battles, and the Prophet (peace and blessings be upon him) ordered him to make a nose of silver. When it gave off a bad smell, he permitted him to make a nose of gold instead. This indicates that removing a defect is permissible, while doing it for beautification is not permissible. May Allah reward you, Honorable Shaykh, and may Allah bless you and your knowledge, and benefit the Muslims through you.
