Sahih al-Bukhari 1807

It is related from Nafi' that 'Ubaydullah and Salim ibn 'Abdullah informed him that in the nights when the army was attacking Ibn az-Zubayr, they said to 'Abdullah ibn 'Umar, "It will not harm you not to go on hajj this year. We fear that they will come between you and the House." He said, "We went out with the Messenger of Allah, may Allah bless him and grant him peace, when the unbelievers of Quraysh were between him and the House. The Prophet, may Allah bless him and grant him peace, sacrificed his sacrificial animal and shaved his head. I testify to you that I have gone into ihram to do 'umra. If Allah wills, I will go and if the way is clear between me and the House, I will do tawaf. If something comes between me and it, I will do as the Prophet, may Allah bless him and grant him peace, did when I was with him." He went into ihram for 'umra from Dhu'l-Hulayfa and then travelled for a time and then said, "They are the same. I testify to you that I have gone into ihram for 'umra and hajj." He did not come out of ihram until the Day of Sacrifice and he had made his sacrifice. He used to say, "You cannot come out of ihram until you have done one tawaf on the day you enter Makka." It is related from Nafi' that some of the Banu 'Abdu'l-Muttalib said to him, "If only you had stayed [home] that year."
