Narrated Ibn 'Umar
During the last Hajj (Hajjat-ul-Widâ') of Allâh's Messenger (ﷺ) he performed ' Umra and Ḥajj together and offered Hady (sacrificial animal) which he drove along with him from Dhul-Hulaifa. Allâh's Messenger (ﷺ) started by assuming for Umra and Ḥajj together and offered Hady (sacrifice). And the people, too, performed the Umra and Ḥajj together along with the Prophet (ﷺ) Some of them brought the Hady and drove it along with them, while the others did not. So, when the Prophet (ﷺ) arrived at Makka he said to the people, "Whoever among you had driven the Hady; would not finish his till he completes his Hajj. And whoever among you has not (driven) the Hady with him, should perform of the Ka'ba and the Sa'y (Tawaf) between-Şafa and Al-Marwa, then cut short his head-hair and finish his and should later assume for Ḥajj; but he must offer a Hady (sacrifice); and if anyone cannot afford a Hady, he should fast for three days during the Hajj and seven days when he returns home. (Hajj-at-Tamattu). [2:750 (A)-O.B.]
