أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ بَزِيعٍ، قَالَ حَدَّثَنَا يَزِيدُ، - وَهُوَ ابْنُ زُرَيْعٍ - قَالَ حَدَّثَنَا خَالِدٌ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُسْأَلُ أَيَّامَ مِنًى فَيَقُولُ " لاَ حَرَجَ " . فَسَأَلَهُ رَجُلٌ فَقَالَ حَلَقْتُ قَبْلَ أَنْ أَذْبَحَ . قَالَ " لاَ حَرَجَ " . فَقَالَ رَجُلٌ رَمَيْتُ بَعْدَ مَا أَمْسَيْتُ . قَالَ " لاَ حَرَجَ " .
