From Sahih Muslim (Hadith 2978):
Imran b. Husain (Allah be pleased with him) reported:We performed Tamattu' (Hajj and 'Umra combining together) in the company of Allah's Messenger (ﷺ), and nothing was revealed in the Qur'an (concerning the abrogation of this practice), and whatever a person (Hadhrat 'Umar) said was his personal opinion. 'Imran b. Husain narrated this hadith (in these words also):" Allah's Apostle (ﷺ) performed Hajj Tamattu' and we also performed it along with him
