The ruling on whoever intended the Hajj of Al-Ifrad then he wants to perform Hajj of At-Tamattu'

Question :

What is the ruling on whoever intended to perform Hajj of Al-Ifrad, then after his arrival in Makkah, he changed it to a Tamattu' Hajj and performed 'Umrah and came out of Ihram from the 'Umrah? What is due on him and when does he assume Ihram for the Hajj and where does he assume the Ihram?

Answer:

This is better if a person came assuming Ihram for Hajj or Hajj and Umrah together. It is better that he makes it an 'Umrah. This is that which the Prophet ordered his Companions to do when they came. Some of them were performing the Hajj of Qiran and some of them were performing the Hajj of Ifrad, and they did not have sacrificial animals with them. Thus, the Prophet ordered them to make their Hajj an Umrah. Hence, they performed Tawaf and Say, got their hair cut and removed their Ihram, except for those who had their sacrificial animals with them. Whoever had has sacrificial animal with him, he remains in his Ihram until he completes the rites of both of them (i.e., the Hajj and the 'Umrah) if he is a Qarin, or the rites of the Hajj if he has assumed Ihram for Hajj only. This takes place on the day of the 'Eid.

What is intended is that whoever comes to Makkah assuming Ihram for Hajj alone or for Hajj and Umrah together, and he does not have a sacrificial animal with him, then the Sunnah is that he changes his Ihram to being for 'Umrah. He then performs Tawaf and Sa'y, gets his hair cut and removes his Ihram. Then he assumes Ihram again for Hajj when its time comes (i.e., the 8th. of Thul-Hijjah). He is then a Mutamatti' and he must make the sacrifice of At-Tamattu'.
