Sahih al-Bukhari, Hadith 1735 ⓘ

Narrated Ibn `Abbas: The Prophet was asked (as regards the ceremonies of Hajj) at Mina on the Day of Nahr and he replied that there was no harm. Then a man said to him, "I got my head shaved before slaughtering." He replied, "Slaughter (now) and there is no harm in it." (Another) man said, "I did the Rami (of the Jimar) after midday." The Prophet replied, "There was no harm in it."

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا خَالِدٌ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم يُسْأَلُ يَوْمَ النَّحْرِ بِمِنًى، فَيَقُولُ ‏"‏ لاَ حَرَجَ ‏"‏‏.‏ فَسَأَلَهُ رَجُلٌ، فَقَالَ حَلَقْتُ قَبْلَ أَنْ أَذْبَحَ‏.‏ قَالَ ‏"‏ اذْبَحْ، وَلاَ حَرَجَ ‏"‏‏.‏ وَقَالَ رَمَيْتُ بَعْدَ مَا أَمْسَيْتُ‏.‏ فَقَالَ ‏"‏ لاَ حَرَجَ ‏"‏‏.‏
