Does a woman shorten her hair for every 'Umrah, or is doing it once sufficient?

Question : She says: Shaykh, does a woman have to shorten her hair by the length of a finger for every 'Umrah she performs, or does she shorten it once for all the 'Umrahs she has performed?

Answer : It is obligatory for a woman to shorten her hair by the length of a finger for every 'Umrah. However, it is known that one does not perform two 'Umrahs in a single journey. In other words, if a person performs an 'Umrah as soon as he arrives in Makkah, he does not perform another one, contrary to what some people do. You may find someone who performs an 'Umrah as soon as he arrives, then performs a second one a day or two later, and a third one a day or two after that. He may even perform 'Umrah every day, or twice in one day. All of this is contrary to the objective of the righteous Salaf. Therefore, we say that whenever a woman performs 'Umrah, she is required to shorten her hair. Likewise, if she performs Hajj, and likewise, a man is required to either shorten his hair or shave it.
