Narrated Nafi`: `Abdullah bin `Umar set out for Umra during the period of afflictions, and he said, "If I should be stopped from visiting the Ka`ba, I will do what we did when we were with Allah's Apostle." He assumed Ihram for `Umra in the year of Al-Hudaibiya.

Narrated Nafi`: `Abdullah bin `Abdullah bin `Umar and his riding animal entered the house of Ibn `Umar. He (the son of Ibn `Umar) said, "I fear that this year a battle might take place between the people and you might be prevented from going to the Ka`ba. I suggest that you should stay here." Ibn `Umar said, "Once Allah's Apostle set out for the pilgrimage, and the pagans of Quraish intervened between him and the Ka`ba. So, if the people intervened between me and the Ka`ba, I would do the same as Allah's Apostle had done . . . "Verily, in Allah's Apostle you have a good example." Then he added, "I make you a witness that I have intended to perform Hajj along with `Umra." After arriving at Mecca, Ibn `Umar performed one Tawaf only (between Safa and Marwa).

Narrated Nafi`: When `Abdullah bin `Umar set out for Mecca intending to perform Umra, at the time of afflictions, he said, "If I should be prevented from reaching the Ka`ba, then I would do the same as Allah's Apostle did, so I assume the lhram for Umra as Allah's Apostle assumed the Ihram for Umra in the year of Hudaibiya."

Narrated Ibn `Abbas: Allah's Apostle was prevented from performing (`Umra) Therefore, he shaved his head and had sexual relations with his wives and slaughtered his Hadi and performed Umra in the following year.
