We entered into the state of Ihram with Allah's Messenger (ﷺ) for Hajj Mufrad and in the narration of Ibn 'Aun (the words are):" Allah's Messenger (ﷺ) entered into the state of Ihram (with the intention) of Hajj Mufrad."
Sahih Muslim Book 15, Hadith 202
← Previous Hadith They would bar you (from going) to the House. He said: In that, case I would do what Allah's Messenger (ﷺ) had done. He did not mention at the end of this hadith (i. e. these words):" This is how the Messenger of Allah (ﷺ) had done," as it Is narrated by al-Laith.

Sahih Muslim Book 15, Hadith 201 Next Hadith → I heard Allah's Apostle (way peace be upon him) pronouncing Talbiya for both Hajj and Umra. Bakr (one of the narrators) said: I narrated it to Ibn 'Umar, whereupon he said: He (the Holy Prophet) pronounced the Talbiya for Hajj alone. I met Anas and narrated to him the words of Ibn 'Umar, whereupon he said: You treat us not but only as children. I heard Allah's Messenger (ﷺ) pronouncing Talbiya both for 'Umra and Hajj.
