Sunan an-Nasa'i, Volume 3, Book 24, Hadith 2771 (DarusSalam) ⓘ

It was narrated from Salim, from his father, that: he used to denounce stipulating conditions in Hajj and said: "Is not the Sunnah of your Prophet sufficient for you? If one of you is prevented (from completing Hajj) by anything, let him come to the House and circumambulate it, and (perform Sai) between As-Safa and Al-Marwah, then let him shave his head or cut his hair, then exit Ihram; and he has to perform Hajj the next year."

أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا عَبْدُ الرَّزَّاقِ، قَالَ أَنْبَأَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، أَنَّهُ كَانَ يُنْكِرُ الاِشْتِرَاطَ فِي الْحَجِّ وَيَقُولُ مَا حَسْبُكُمْ سُنَّةُ نَبِيِّكُمْ صلى الله عليه وسلم إِنَّهُ لَمْ يَشْتَرِطْ فَإِنْ حَبَسَ أَحَدَكُمْ حَابِسٌ فَلْيَأْتِ الْبَيْتَ فَلْيَطُفْ بِهِ وَبَيْنَ الصَّفَا وَالْمَرْوَةِ ثُمَّ لْيَحْلِقْ أَوْ يُقَصِّرْ ثُمَّ لْيُحْلِلْ وَعَلَيْهِ الْحَجُّ مِنْ قَابِلٍ ‏.‏
