You could use Named Blocks here for Arabic characters.

Example:

Regex.IsMatch(txtName, @"(\p{IsArabic}+(\s)?)+");

This will match the pattern of one or more Arabic characters followed by zero or one white-space characters one or more times. Tested as working with your input string.

Here's a more in depth reference from MSDN with additional examples.

@"^[آ-ی]$"

I don't think you want to mach only strings with a single char, so try

@"^[آ-ی]+$"
