Is a blood sacrifice obligatory for whoever assumes the state of ihram for Umrah from Ta'if or from the Miqat of Sail al-Kabeer, given that it is difficult for him to return to the Miqat of Rabigh due to his old age?

Those arriving for 'Umrah must enter into ihram from the Miqat they pass through, whether by land or air, based on the Prophet, peace and blessings be upon him, who said: "They are for them and for anyone else who comes by them from other than their people, intending Hajj or 'Umrah."
