whether or not
Also, whether or no. Regardless of whether, no matter if. For example, Whether or not it rains, we're going to walk to the theater, or She plans to sing at the wedding, whether or no anyone asks her to. The negative element in these constructions may also follow the subject and verb, as in I have to attend, whether I want to or not. [c. 1600]
