"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
