(Abdullah) bin ʿUmar used to say, "Is not (the following of) the tradition of Messenger of Allah ﷺ sufficient for you? If anyone of you is prevented from performing Hajj, he should perform the Tawaf of the Kaʿba 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."  

كَانَ ابْنُ عُمَرَ ؓ يَقُولُ أَلَيْسَ حَسْبُكُمْ سُنَّةَ رَسُولِ اللَّهِ ﷺ 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
