It is not clear what flavor of regex you need, but in the general, one of the following should work:

^[^0-9]*$
^[^\d]*$
^\D*$
^[[:^digit:]]*$
^\P{IsDigit}*$

The last two forms will work with Unicode digits.

The atom [^0-9] matches anything but a digit; to make sure that in the whole string there are no digits, I added the markers of string start (^) and end ($).

If you want to match any part of a string that contains at least one character that is not a digit, replace the ^...*$ part of the regex by ...+:

[^0-9]+
\D+

etc.

Try [^0-9]+. Note that this will only prevent ASCII digits from appearing, not unicode ones.
