Sunan Abi Dawud, Hadith 1978

Narrated Ibn 'Abbas: The Prophet was asked (about rites of Hajj) on the day of stay at Mina. He said: No harm. A man asked him: I got myself shaved before I slaughtered. He said: Slaughter, there is no harm. He again asked: The evening came but I did not throw stones at the jamrah. He replied: Throw stones now ; there is no harm.

حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ، أَخْبَرَنَا يَزِيدُ بْنُ زُرَيْعٍ، أَخْبَرَنَا خَالِدٌ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يُسْأَلُ يَوْمَ مِنًى فَيَقُولُ ‏"‏ لاَ حَرَجَ ‏"‏ ‏.‏ فَسَأَلَهُ رَجُلٌ فَقَالَ إِنِّي حَلَقْتُ قَبْلَ أَنْ أَذْبَحَ ‏.‏ قَالَ ‏"‏ اذْبَحْ وَلاَ حَرَجَ ‏"‏ ‏.‏ قَالَ إِنِّي أَمْسَيْتُ وَلَمْ أَرْمِ ‏.‏ قَالَ ‏"‏ ارْمِ وَلاَ حَرَجَ ‏"‏ ‏.‏
