Some scholars have stated that the ritual of ifrad in Hajj is superior to all other forms of Hajj in one specific case. What is that case?

Question:
He says: Honorable Shaykh, may Allah grant you success. Some scholars have stated that the ritual of ifrad in Hajj is superior to all other forms of Hajj in one specific case: if a person performs 'Umrah during the months of Hajj, then returns to his country, and then travels to perform Hajj alone (ifrad) in that same year. They claim that this is the consensus of the scholars and that it is the view of Shaykh al-Islam Ibn Taymiyyah. He asks: Is what they mentioned correct?

Answer:
By Allah, I have not come across the statement of Shaykh al-Islam that they are referring to. However, they are agreed that tamattu' is superior. This is because the Messenger (peace and blessings be upon him) expressed a wish for it, saying: "If I had known in advance what I know now, I would have exited the state of ihram with you and not made it an 'Umrah." The Messenger (peace and blessings be upon him) wished for tamattu', and he would not wish for anything except what is best. Yes.
