"Ibn 'Umar used to denounce stipulating conditions in Hajj, and said: 'Is not the Sunnah of the Messenger of Allah sufficient for you? If one of you is prevented from performing (finishing) Hajj let him circumambulate the House and (perform Sai) between As-Safa and al-Marwah, then exit Ihram completely until he performs Hajj the following year. And let him offer a Hadi or fast if he con not find a Hadi. (Using translation from Nasāʾī 2769)   

كَانَ عَبْدُ اللهِ بْنُ عُمَرَ ؓ يُنْكِرُ الِاشْتِرَاطَ فِي الْحَجِّ وَيَقُولُ أَلَيْسَ حَسْبُكُمْ سُنَّةَ رَسُولِ اللهِ ﷺ؟ إِنْ حُبِسَ أَحَدُكُمْ عَنِ الْحَجِّ طَافَ بِالْبَيْتِ وَبِالصَّفَا وَالْمَرْوَةِ ثُمَّ حَلَّ مِنْ كُلِّ شَيْءٍ حَتَّى حَجَّ عَامًا قَابِلًا وَيُهْدِيَ أَوْ يَصُومَ إِنْ لَمْ يَجِدْ قَالَ يُونُسُ قَالَ رَبِيعَةُ لَا نَعْلَمُ شَرْطًا يَجُوزُ فِي إِحْرَامِهِ  

[Machine] He used to deny the requirement in Hajj and would say, "Is it not sufficient for you the Sunnah of the Messenger of Allah ﷺ ?" Abu Amr Al-Adibi informed us that Abu Bakr Al-Isma'ili informed us that I am the son of Najiyyah. They narrated to us from Ahmad ibn Mani'a, Al-Hasan ibn 'Arfatah, and 'Ali ibn Muslim. They said: Abd Allah ibn Al-Mubarak narrated to us from Ma'mar from Al-Zuhri, and he mentioned it similarly.  

أَنَّهُ كَانَ يُنْكِرُ الِاشْتِرَاطَ فِي الْحَجِّ وَيَقُولُ أَلَيْسَ حَسْبُكُمْ سُنَّةَ رَسُولِ اللهِ ﷺ؟ 10125 وَأَخْبَرَنَا أَبُو عَمْرٍو الْأَدِيبُ أنا أَبُو بَكْرٍ الْإِسْمَاعِيلِيُّ أنا ابْنُ نَاجِيَةَ ثنا أَحْمَدُ بْنُ مَنِيعٍ وَالْحَسَنُ بْنُ عَرَفَةَ وَعَلِيُّ بْنُ مُسْلِمٍ قَالُوا ثنا عَبْدُ اللهِ بْنُ الْمُبَارَكِ عَنْ مَعْمَرٍ عَنِ الزُّهْرِيِّ فَذَكَرَهُ بِمِثْلِهِ
