Musnad Ahmad Hadith 2351

O Abul-'Abbas, what about what you said, that there is no man who performed Hajj and who did not bring his sacrificial animal with him, then he circumambulated the House, but he should exit ihram and regard what he has done as 'Umrah, and there is no pilgrim who brought his sacrificial animal with him and circumambulated the House, but he should combine 'Umrah and Hajj - but the people do not say this? He said: Woe to you! The Messenger of Allah (ﷺ) and those of his Companions who were with him set out, not thinking of anything except Hajj, then the Messenger of Allah (ﷺ) instructed those who did not have a sacrificial animal with them to circumambulate the House and exit ihram on the basis that what they had done was ‘Umrah. One of them said: O Messenger of Allah, rather it is Hajj. The Messenger of Allah (ﷺ) said: "It is not Hajj; rather it is 'Umrah."
