Nafi reported,

Ibn Umar's son, Abdullah bin Abdullah, came in to him while his mount was standing in the courtyard and said, "I fear that this year there will be fighting among the people and they will block you from reaching the House. It would be better if you stayed."Ibn Umar replied, "The Messenger of Allah ﷺ set out, and the disbelievers of Quraysh came between him and the House. If I am prevented from reaching it, I will do as the Messenger of Allah ﷺ did. 'You have had an excellent example in the Messenger of Allah' [Ahzab 33:21]."Then he said, "I call you to witness that I have made hajj obligatory upon myself along with my umrah."He then arrived and made a single tawaf for both.

حدثنا يعقوب بن إبراهيم حدثنا ابن علية عن أيوب

عن نافع

أن ابن عمر رضي الله عنهما دخل ابنه عبد الله بن عبد الله وظهره في الدار فقال إني لا آمن أن يكون العام بين الناس قتال فيصدوك عن البيت فلو أقمت فقال قد خرج رسول الله ﷺ فحال كفار قريش بينه وبين البيت فإن حيل بيني وبينه أفعل كما فعل رسول الله ﷺ {لقد كان لكم في رسول الله إسوة حسنة} ثم قال أشهدكم أني قد أوجبت مع عمرتي حجا قال ثم قدم فطاف لهما طوافا واحدا
