Sahih al-Bukhari, Volume 2, Book 26, Hadith 703 (USC-MSA) ⓘ

Narrated Nafi`: `Abdullah bin `Abdullah bin `Umar and his riding animal entered the house of Ibn `Umar. He (the son of Ibn `Umar) said, "I fear that this year a battle might take place between the people and you might be prevented from going to the Ka`ba. I suggest that you should stay here." Ibn `Umar said, "Once Allah's Messenger set out for the pilgrimage, and the pagans of Quraish intervened between him and the Ka`ba. So, if the people intervened between me and the Ka`ba, I would do the same as Allah's Messenger had done... "Verily, in Allah's Messenger you have a good example." Then he added, "I make you a witness that I have intended to perform Hajj along with `Umra." After arriving at Mecca, Ibn `Umar performed one Tawaf only (between Safa and Marwa).

حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا ابْنُ عُلَيَّةَ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، أَنَّ ابْنَ عُمَرَ ـ رضى الله عنهما ـ دَخَلَ ابْنُهُ عَبْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ، وَظَهْرُهُ فِي الدَّارِ، فَقَالَ إِنِّي لاَ آمَنُ أَنْ يَكُونَ الْعَامَ بَيْنَ النَّاسِ قِتَالٌ، فَيَصُدُّوكَ عَنِ الْبَيْتِ، فَلَوْ أَقَمْتَ‏.‏ فَقَالَ قَدْ خَرَجَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَحَالَ كُفَّارُ قُرَيْشٍ بَيْنَهُ وَبَيْنَ الْبَيْتِ، فَإِنْ حِيلَ بَيْنِي وَبَيْنَهُ أَفْعَلُ كَمَا فَعَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏{‏لَقَدْ كَانَ لَكُمْ فِي رَسُولِ اللَّهِ أُسْوَةٌ حَسَنَةٌ‏}‏ ثُمَّ قَالَ أُشْهِدُكُمْ أَنِّي قَدْ أَوْجَبْتُ مَعَ عُمْرَتِي حَجًّا‏.‏ قَالَ ثُمَّ قَدِمَ فَطَافَ لَهُمَا طَوَافًا وَاحِدًا‏.‏
