أَخْبَرَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ، وَالْحَارِثُ بْنُ مِسْكِينٍ، قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ، عَنِ ابْنِ وَهْبٍ، قَالَ أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمٍ، قَالَ كَانَ ابْنُ عُمَرَ يُنْكِرُ الاِشْتِرَاطَ فِي الْحَجِّ وَيَقُولُ أَلَيْسَ حَسْبُكُمْ سُنَّةُ رَسُولِ اللَّهِ صلى الله عليه وسلم إِنْ حُبِسَ أَحَدُكُمْ عَنِ الْحَجِّ طَافَ بِالْبَيْتِ وَبِالصَّفَا وَالْمَرْوَةِ ثُمَّ حَلَّ مِنْ كُلِّ شَىْءٍ حَتَّى يَحُجَّ عَامًا قَابِلاً وَيُهْدِي وَيَصُومُ إِنْ لَمْ يَجِدْ هَدْيًا ‏.‏
