The ruling on one who exits the state of ihram by cutting one or two hairs?

Question : The questioner says: Many of those performing 'Umrah leave off shaving and shortening the hair, and perhaps they cut a few countable hairs that the eye cannot detect.

Answer : What the questioner mentioned is a reality, for some of those performing 'Umrah and some of the pilgrims also do not shorten or shave; they do not shave their heads nor shorten them either, but rather they cut from them three hairs or one hair or something similar. This is not balanced, because so it is clear that it is necessary to shave the entire head and to shorten, which is called shortening and its effect appears on the head. As for taking one or two hairs, if you compared this man who took one or two hairs from his head before he took them or after he took them, you would find his head in a state of uniformity, with no effect of shortening appearing on his head. Accordingly, this action is not sufficient, and it is obligatory for them to shorten in place of the first erroneous action. And among the wonders I have seen is that I saw a man who had shaved half of his head lengthwise; the right side of the head was shaved, and the other side was invalid. So I asked him why he does this, and it is of the qaza' (shaving part of the head) which is prohibited? He said: This shaving I did in the first 'Umrah, and the rest of the head will be shaved in the second 'Umrah. So reflect, my brother, how this action has led to this repetition of 'Umrah with this great error?
It means a clear mutilation on the head of this man, walking among the people with half his head shaved and the other half intact, based on the fact that he will come with a second 'Umrah to shave the rest of his head. And this is darkness upon darkness. We ask Allah for safety.
