Ihram for Hajj for one who entered Makkah without Ihram

The questioner:
Honorable Shaykh, may Allah grant you success, he says: I am from the people of Riyadh and I want to perform Hajj this year, if Allah wills. I am from the people of Riyadh.

The Shaykh:
Yes.

The questioner:
And I want to perform Hajj this year, if Allah wills, and I will go at the beginning of the month of Dhul-Hijjah. His question is: If I enter Makkah without entering the state of Ihram, do I return to the Miqat of al-Sail al-Kabir, or do I go to al-Tan'if if I want to enter the state of Ihram for Hajj?

The Shaykh:
If you go to Makkah intending Hajj or 'Umrah and you pass the Miqat, you must enter the state of Ihram from the Miqat, and if you pass it, you return to it. However, if you pass the Miqat while not intending Hajj or 'Umrah, and then you decide to perform 'Umrah or Hajj after passing the Miqat, you enter the state of Ihram from the place where you made the intention.
Unless you intend 'Umrah and make the intention from Makkah; then you do not enter the state of Ihram for 'Umrah from Makkah. You must go out to the non-sacred area (Hill) and enter the state of Ihram from the Hill, from al-Tan'if or elsewhere. One does not enter the state of Ihram for 'Umrah from Makkah.
As for Hajj, one enters the state of Ihram from Makkah and from outside Makkah. Because Hajj combines the non-sacred area (Hill) and the sacred precinct (Haram), as one will go out to Mina and to 'Arafah. As for 'Umrah, all its acts are within the sacred precinct, so it must combine the non-sacred area and the sacred precinct. Yes.
