Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)

Bukhari :: Book 5 :: Volume 59 :: Hadith 499

Narrated Nafi:

One of 'Abdullah's sons said to 'Abdullah (bin Umar) "I wish you would stay this year (and not perform Hajj) as I am afraid that you will not be able to reach the Kaba." On that he (i.e. 'Abdullah bin Umar) said, "We went out with the Prophet (for 'Umra), and when the Quraish infidel intervened between us and the Ka'ba, the Prophet slaughtered his Hadi and shaved (his head), and his companions cut short their hair." Then 'Abdullah bin Umar said, "I make you witness that I have intended to perform 'Umra and if I am allowed to reach the Kaba, I will perform the Tawaf, and if something (i.e. obstacles) intervene between me and the Kaba, then I will do what Allah's Apostle did." Then after going for a while, he said, "I consider the ceremonies (of both 'Umra and Hajj as one and the same, so I would like you to witness that I have intended to perform Hajj along with my 'Umra." So he performed only one Tawaf and one Sai (between Safa and Marwa) and finished the Ihram of both Umra and Hajj).
