Sahih al-Bukhari, Hadith 1810 ⓘ

Narrated Salim: (Abdullah) bin `Umar used to say, "Is not (the following of) the tradition of Allah's Messenger sufficient for you? If anyone of you is prevented from performing Hajj, he should perform the Tawaf of the Ka`ba and between As-Safa and Al-Marwa and then finish the Ihram and everything will become legal for him which was illegal for him (during the state of Ihram) and he can perform Hajj in a following year and he should slaughter a Hadi or fast in case he cannot afford the Hadi."

حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا يُونُسُ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي سَالِمٌ، قَالَ كَانَ ابْنُ عُمَرَ ـ رضى الله عنهما ـ يَقُولُ أَلَيْسَ حَسْبُكُمْ سُنَّةَ رَسُولِ اللَّهِ صلى الله عليه وسلم، إِنْ حُبِسَ أَحَدُكُمْ عَنِ الْحَجِّ طَافَ بِالْبَيْتِ وَبِالصَّفَا وَالْمَرْوَةِ، ثُمَّ حَلَّ مِنْ كُلِّ شَىْءٍ، حَتَّى يَحُجَّ عَامًا قَابِلاً، فَيُهْدِي أَوْ يَصُومُ، إِنْ لَمْ يَجِدْ هَدْيًا‏.‏ وَعَنْ عَبْدِ اللَّهِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، قَالَ حَدَّثَنِي سَالِمٌ، عَنِ ابْنِ عُمَرَ، نَحْوَهُ‏.‏
