English translation
1813. Narrated Nāfi': When 'Abdullāh bin 'Umar رضي الله عنهم set out for Makkah with the intention of performing 'Umra in the period of Al-Fitnah (trial and affliction), he said, "If I should be prevented from reaching the Ka'bah, then I would do the same as we did while in the company of Allāh's Messenger ﷺ." So, he assumed the Iḥrām for 'Umra since the Prophet ﷺ had assumed the Iḥrām for 'Umra in the year of Al-Ḥudaibiya. Then 'Abdullāh bin 'Umar thought about it and said, "The conditions for both Hajj and Umra are similar." He then turned towards his companions and said, "The conditions of both Hajj and Umra are similar and I make you witness that I have made the performance of Hajj obligatory for myself along with Umra." He then performed one Tawāf [Ṣā'y (going) between Aṣ-Ṣafā and Al-Marwa] for both of them (i.e., Hajj and Umra) and considered that to be sufficient for him and offered a Hady.
