Ibn Abbas (RA) reported that Allah's Messenger (ﷺ) observed the morning prayer at Dhu Tawa (a valley near Makkah) and arrived (in Makkah) when four days of Dhul-Hijja had passed and he commanded his Companions that they should change their Ihram (of Hajj) to that of 'Umrah, except those who had brought sacrificial animals with them.
