I need regular expression which allow only alphabets of any language but doesn't allow special characters and numbers.

You can use \p{L} which matches any kind of letter from any language.

^[\p{L}\s]{1,50}$

If you need to match ' and dot . as well, just add them to the character class.

^[\p{L}\s'.]{1,50}$
