Is it permissible for a person to enter the state of ihram in the same manner as another person, without knowing what that person intended?

Question : Is it permissible for a person to enter the state of ihram in the same manner as another person, without knowing what that person intended?

Answer : The answer is yes, because Abu Musa al-Ash'ari (may Allah be pleased with him) entered the state of ihram in the same manner as the Prophet (peace and blessings be upon him and his family), and likewise 'Ali ibn Abi Talib entered the state of ihram in the same manner as the Prophet (peace and blessings be upon him and his family). Therefore, if a person is confident in another man's knowledge and religion, and enters the state of ihram in the same manner as him, there is no blame on him, because this is an action that the Prophet (peace and blessings be upon him and his family) permitted. However, the Prophet (peace and blessings be upon him and his family) ordered Abu Musa to exit the state of ihram as one performing tamattu', whereas regarding 'Ali, he said to him, "I have the sacrificial animals with me, so do not exit the state of ihram." So the Prophet (peace and blessings be upon him and his family) included him in his sacrificial animals, and he did not exit the state of ihram, because one who brings sacrificial animals cannot exit the state of ihram before the animals reach their place of sacrifice.
If he is unaware of what that person intended by entering the state of ihram, meaning he did not agree with that person until he reached Makkah and did not know what to make of it, we say the best is to make it an 'Umrah, because if it is assumed that he entered the state of ihram for Hajj, then canceling the Hajj and making it an 'Umrah is permissible, and this is the best course of action, because the Prophet (peace and blessings be upon him) ordered his companions to make it an 'Umrah. Yes, although in our time, I think, this is rarely encountered.
