What is the ruling on shortening only part of the hair?

Question:
The questioner says: What is the ruling on the one who did not shorten the hair on his entire head during Hajj or 'Umrah? I know that I see many people who do this, and I read in the book *Islamic Awareness* published by the Presidency of Scientific Research, Ifta, and Guidance, because

Answer:
it is obligatory in shortening the hair to cover the entire head, and shortening only part of it is not sufficient. However, many people I know say that they asked and were told that shortening from one side is sufficient, according to the opinion of some scholars. We ask for your ruling. May Allah reward you with good. After the Committee studied the question, it answered as follows: It is obligatory for the one who wants to exit the state of ihram from his 'Umrah or Hajj by shortening the hair to cover the entirety of the hair on his head. Allah the Exalted said: "Shaving your heads or shortening them." The command is for emulation. It is established from the Prophet (peace and blessings be upon him) that he said: And he commanded shaving or shortening. As for what has passed from you regarding not covering the entire head, Allah will forgive it, if Allah wills, due to the well-known disagreement among the scholars on this matter. In the future, cover your head with shortening in Hajj or 'Umrah, knowing that shaving is better, as established in the two Sahihs from the supplication of the Prophet (peace and blessings be upon him) for those who shaved three times, then he said: "And for those who shortened." And success is from Allah.
