The Prophet (may Allah's peace and blessings be upon him) went out for Hajj in the tenth year, in Dhul-Hijjah. It was called the Farewell Hajj. The Prophet (may Allah's peace and blessings be upon him) commanded some of his Companions, after they had come to Makkah and performed Tawāf around the House and Sa‘i between Safa and Marwah, to end their Hajj and turn it into ‘Umrah, which was called Tamattu‘ in performing ‘Umrah before Hajj. In this Hadīth, ‘Abdullāh ibn ‘Abbās (may Allah be pleased with him) mentions that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "This is an ‘Umrah which we have treated as Tamattu‘"; thereby, he refers to the command he gave to some of his Companions (may Allah be pleased with them) to end their Hajj and turn it into ‘Umrah. Meanwhile, the Prophet (may Allah's peace and blessings be upon him) was in a state of Qirān, performing ‘Umrah along with Hajj, and he did not end his Hajj to turn it into ‘Umrah along with them. However, he attributed Tamattu‘ to himself because he was the one who commanded them to do so and approved it for them. Those who were commanded to engage in Tamattu‘ were those who did not have the sacrificial animals, a term that refers to cattle, such as camels, cows, and sheep, that are offered at the Ka‘bah as a means of closeness to Allah. He (may Allah's peace and blessings be upon him) ordered them to end Ihrām completely, i.e., all the things forbidden because of Ihrām were then permissible for them. Then, clarifying the reason behind his command about ending Ihrām, he (may Allah's peace and blessings be upon him) said that ‘Umrah was incorporated into Hajj until the Day of Judgment, i.e., ‘Umrah can be performed in the months of Hajj, unlike the past practice of the people of Jāhiliyyah. The intention for ‘Umrah was incorporated into the intention for Hajj, such that if a person intends to perform Hajj, it becomes legitimate for him to end Hajj by the performance of ‘Umrah, in case he did not bring the sacrificial animals with him. As for those who bring the sacrificial animals with them, they should remain in their Ihrām until the completion of the rituals of Hajj, and this is called Qirān Hajj. The Hadīth shows that ‘Umrah can be performed in the months of Hajj..
