هل تُعد السخرية من شكل فنان في مسلسل غِيبة؟

It is not permissible to mock anyone's appearance, whether they are an actor or otherwise, because Allah Almighty says: ﴿O YOU WHO HAVE BELIEVED, LET NOT A PEOPLE MOCK [ANOTHER] PEOPLE; PERHAPS THEY MAY BE BETTER THAN THEM; NOR LET WOMEN MOCK [OTHER] WOMEN; PERHAPS THEY MAY BE BETTER THAN THEM.﴾ [Al-Hujurat: 11]. If mocking someone's appearance involves mentioning something they dislike, then this is considered forbidden backbiting, unless the person has openly committed transgression.
