The second objection is that his words, “That is indeed for ever and ever,” refer only to the permissibility of performing ‘umrah during the months of Hajj. This objection is even more untenable than the first. The questioner was asking the Prophet, peace and blessings be upon him, about tamattu‘—converting Hajj into ‘umrah—not about the permissibility of ‘umrah during the months of Hajj. He asked only just after (1) the Prophet had instructed those who had no sacrificial animal with them to convert their Hajj into ‘umrah. He then said to him (2): “Is this for this year of ours (3), or for all time?” The Prophet, peace and blessings be upon him, answered the very question he had asked, not something he had not asked about.
His words, “‘Umrah has become part of Hajj until the Day of Resurrection,” spoken immediately after instructing those who had no sacrificial animal with them to leave the state of ritual consecration, are a clear indication (4) that this continues until the Day of Resurrection. The claim that it was exclusive to them is therefore invalid. Success comes from Allah alone.
Sixth: This rationale (5) that you have mentioned is neither stated nor alluded to in the hadith. If it is invalid, your objection based upon it is invalid. If it is valid, it does not entail (6), in any way whatsoever, that this was exclusive to the Companions. Rather, if valid, it would require its effect to remain in force and continue. Likewise, brisk walking during circumambulation was prescribed so that he could show the polytheists his strength and that of his Companions, yet it remains prescribed until the Day of Resurrection. Thus, under either assumption, appealing to that rationale to establish exclusivity to the Companions is invalid.
