Did all the Companions walk between the two hills to the right and left of the Prophet, thereby indicating that the Sa'i has no specific width?

Question:
May Allah reward you, Honorable Shaykh. A questioner says: Some people have argued, based on what is reported regarding the Prophet’s (peace and blessings be upon him) Hajj, that the people were to his right and to his left as far as the eye could see, to prove that the Sa'i has no specific width. What is the validity of this argument?

Answer:
Who said that they all walked together? Who said this? Prove to us that they all walked together to his right and to his left. He cannot do this; he cannot prove that one hundred thousand or more walked at the same time to his right and to his left. Yes, this is an argument based on forced reasoning. Yes.
