Sahih al-Bukhari 4185

It is related from Nafi' that 'Ubaydullah ibn 'Abdullah and Salim ibn 'Abdullah reported that they spoke to 'Abdullah ibn 'Umar. It is related from Nafi' that one of 'Abdullah's sons said to him, "If only you would stay home this year. I fear that you will not reach the House." He answered, "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 animals and shaved his head and his Companions cut their hair short." He said, "I testify to you that I went into ihram to do 'umra. 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 Messenger of Allah, may Allah bless him and grant him peace, did." Then he travelled for a time and then said, "I only think that they are the same. I testify to you that I have gone into ihram for 'umra and hajj." So he only did one tawaf and one sa'y and came out of ihram for both of them.
