It was narrated from Ikrimah, from Al-Hajjaj bin Amr Al-Ansari that:

he heard the Messenger of Allah say "Whoever suffers a leg injury of breaks his leg, he has exited Ihram, but he has to perform another Hajj." I asked Ibn Abbas and Abu Hurarirah about that and he said "He spoke the truth."

أَخْبَرَنَا حُمَيْدُ بْنُ مَسْعَدَةَ الْبَصْرِيُّ، قَالَ حَدَّثَنَا سُفْيَانُ، - وَهُوَ ابْنُ حَبِيبٍ - عَنِ الْحَجَّاجِ الصَّوَّافِ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ عِكْرِمَةَ، عَنِ الْحَجَّاجِ بْنِ عَمْرٍو الأَنْصَارِيِّ، أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ " مَنْ عَرِجَ أَوْ كُسِرَ فَقَدْ حَلَّ وَعَلَيْهِ حَجَّةٌ أُخْرَى " . فَسَأَلْتُ ابْنَ عَبَّاسٍ وَأَبَا هُرَيْرَةَ عَنْ ذَلِكَ فَقَالاَ صَدَقَ .
