Nafi' (may Allah have mercy on him) reports that Sayyiduna Ibn Umar (may Allah be pleased with them both) set out for Makkah with the intention of performing 'Umrah during the days of turmoil, and said: "If any obstacle comes before me, I will do what the Prophet (peace and blessings be upon him) did." Then he made the intention for 'Umrah, because the Prophet (peace and blessings be upon him) had also assumed the Ihram for 'Umrah in the year of Hudaybiyyah.
