Narrated Nafi`:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، أَخْبَرَنَا مَالِكٌ ، عَنْ نَافِعٍ ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ ـ رضى الله عنهما ـ حِينَ خَرَجَ إِلَى مَكَّةَ مُعْتَمِرًا فِي الْفِتْنَةِ قَالَ إِنْ صُدِدْتُ عَنِ الْبَيْتِ صَنَعْتُ كَمَا صَنَعْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم. فَأَهَلَّ بِعُمْرَةٍ، مِنْ أَجْلِ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ أَهَلَّ بِعُمْرَةٍ عَامَ الْحُدَيْبِيَةِ.
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 Messenger (ﷺ) did, so I assume the lhram for Umra as Allah's Messenger (ﷺ) assumed the Ihram for Umra in the year of Hudaibiya."
