question #2 Sahih Muslim 1216d, Book 15, Hadith 155 : How did the presence of sacrificial animals affect the Prophet’s ability to change his Ihram from Hajj to Umra?

We set out with Allah’s Messenger (ﷺ) as Muhrim for Hajj. The Messenger of Allah (ﷺ) commanded us to make this Ihram for Umra, and some put it off (after performing ‘Umra), but the Prophet (ﷺ) had sacrificial animals with him, so he could not make it (this Ihram) as that of Umra.
