What did Allah's Apostle (peace be upon him) do in the year of Hudaibiya to which `Abdullah bin `Umar wanted to refer when he said he would do the same if prevented from reaching the Ka`ba?
 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."
