All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
The existence of a mole in any part of the body is a normal matter and we do not know any Islamic evidence which indicates that it means something special.
As regards the existence of a mole on the cheek whether or not it means beauty, then this matter depends on the traditional norms of the people and their tastes which may vary from one person to another. Some people may think that its existence on the cheek makes one more beautiful, whereas some other people may think that it is not so. For more benefit, please refer to Fatwa 116202.
Allaah Knows best.
