Sahih al-Bukhari 1568

Narrated Abu Shihab:I left for Mecca for Hajj-at-Tamattu` assuming Ihram for `Umra. I reached Mecca three days before the day of Tarwiya (8th Dhul-Hijja). Some people of Mecca said to me, "Your Hajj will be like the Hajj performed by the people of Mecca (i.e. you will lose the superiority of assuming Ihram from the Miqat). So I went to `Ata' asking him his view about it. He said, "Jabir bin `Abdullah narrated to me, 'I performed Hajj with Allah's Messenger (ﷺ) on the day when he drove camels with him. The people had assumed Ihram for Hajj-al-Ifrad. The Prophet (ﷺ) ordered them to finish their Ihram after Tawaf round the Ka`ba, and between Safa and Marwa and to cut short their hair and then to stay there (in Mecca) as non-Muhrims till the day of Tarwiya (i.e. 8th of Dhul-Hijja) when they would assume Ihram for Hajj and they were ordered to make the Ihram with which they had come as for `Umra only. They asked, 'How can we make it `Umra (Tamattu`) as we have intended to perform Hajj?' The Prophet (ﷺ) said, 'Do what I have ordered you. Had I not brought the Hadi with me, I would have done the same, but I cannot finish my Ihram till the Hadi reaches its destination (i.e. is slaughtered).' So, they did (what he ordered them to do)."
