Ibn ʿUmar intended to perform Hajj in the year when Al-Hajjaj attacked Ibn Az-Zubair. Somebody said to Ibn ʿUmar, "There is a danger of an impending war between them." Ibn ʿUmar said, "Verily, in Messenger of Allah ﷺ you have a good example. (And if it happened as you say) then I would do the same as Messenger of Allah ﷺ had done. I make you witness that I have decided to perform ʿUmra." Then he set out and when he reached Al-Baida', he said, "The ceremonies of both Hajj and ʿUmra are similar. I make you witness that I have made Hajj compulsory for me along with ʿUmra." He drove (to Mecca) a Hadi which he had bought from (a place called) Qudaid and did not do more than that. He did not slaughter the Hadi or finish his Ihram, or shave or cut short his hair till the day of slaughtering the sacrifices (10th Dhul-Hijja). Then he slaughtered his Hadi and shaved his head and considered the first Tawaf (of Safa and Marwa) as sufficient for Hajj and ʿUmra. Ibn ʿUmar said, "Messenger of Allah ﷺ did the same." (Using translation from Bukhārī 1640)
لَقَدْ كَانَ لَكُمْ فِي رَسُولِ اللهِ أُسْوَةٌ حَسَنَةٌ إِذًا أَصْنَعُ كَمَا صَنَعُ رَسُولُ اللهِ ﷺ أُشْهِدُكُمْ أَنِّي قَدْ أَوْجَبْتُ عُمْرَةً حَتَّى إِذَا كَانَ بِظَهْرِ الْبَيْدَاءِ قَالَ مَا شَأْنُ الْحَجِّ وَالْعُمْرَةِ إِلَّا وَاحِدٌ أُشْهِدُكُمْ أَنِّي قَدْ أَوْجَبْتُ حَجًّا مَعَ عُمْرَتِي وَأَهْدَى هَدْيًا اشْتَرَاهُ بِقُدَيْدٍ فَانْطَلَقَ فَقَدِمَ مَكَّةَ فَطَافَ بِالْبَيْتِ وَبِالصَّفَا وَالْمَرْوَةِ لَمْ يَزِدْ عَلَى ذَلِكَ لَمْ يَنْحَرْ وَلَمْ يَحْلِقْ وَلَمْ يُقَصَّرْ وَلَمْ يَحْلِلْ مِنْ شَيْءٍ كَانَ أَحْرَمَ مِنْهُ حَتَّى كَانَ يَوْمُ النَّحْرِ فَنَحَرَ وَحَلَقَ وَرَأَى أَنْ قَدْ قَضَى طَوَافَهُ لِلْحَجِّ وَالْعُمْرَةِ بِطَوَافِهِ الْأَوَّلِ قَالَ هَكَذَا صَنَعَ رَسُولُ اللهِ ﷺ
