I saw the Prophet ﷺ near the Jamra and the people were asking him questions (about religious problems). A man asked, "O Messenger of Allah ﷺ! I have slaughtered the Hadi (animal) before doing the Rami." The Prophet ﷺ replied, "Do the Rami (now) and there is no harm." Another person asked, "O Messenger of Allah ﷺ! I got my head shaved before slaughtering the animal." The Prophet ﷺ replied, "Do the slaughtering (now) and there is no harm." So on that day, when the Prophet ﷺ was asked about anything as regards the ceremonies of Hajj performed before or after its due time his reply was, "Do it (now) and there is no harm." (Using translation from Bukhārī 124)  

رَأَيْتُ رَسُولَ اللَّهِ ﷺ عِنْدَ الْجَمْرَةِ وَهُوَ يُسْأَلُ فَقَالَ رَجُلٌ يَا رَسُولَ اللَّهِ نَحَرْتُ قَبْلَ أَنْ أَرْمِيَ؟ قَالَ «ارْمِ وَلَا حَرَجَ» قَالَ آخَرُ يَا رَسُولَ اللَّهِ حَلَقْتُ قَبْلَ أَنْ أَنْحَرَ؟ قَالَ «انْحَرْ وَلَا حَرَجَ» قَالَ فَمَا سُئِلَ عَنْ شَيْءٍ قُدِّمَ وَلَا أُخِّرَ إِلَّا قَالَ «افْعَلْ وَلَا حَرَجَ»  

[Machine] The Messenger of Allah ﷺ stood in front of the people during the Farewell Pilgrimage and a man said to him, "O Messenger of Allah, I have already shaved my head before sacrificing." He ﷺ replied, "There is no harm in that." The man then asked, "I have already slaughtered my animal before throwing pebbles at the Jamarat (stone pillars)." He ﷺ again replied, "There is no harm in that." On that day, he ﷺ was not asked about anything that has been done before or after, except that he ﷺ said, "There is no harm in that." Abdullah said, "I say this, but the people of Kufa differ with me."  

أَنَّ رَسُولَ اللَّهِ ﷺ وَقَفَ لِلنَّاسِ فِي حَجَّةِ الْوَدَاعِ فَقَالَ لَهُ رَجُلٌ يَا رَسُولَ اللَّهِ حَلَقْتُ قَبْلَ أَنْ أَذْبَحَ؟ قَالَ «لَا حَرَجَ» قَالَ لَمْ أَشْعُرْ ذَبَحْتُ قَبْلَ أَنْ أَرْمِيَ؟ قَالَ «لَا حَرَجَ» فَلَمْ يُسْأَلْ يَوْمَئِذٍ عَنْ شَيْءٍ قُدِّمَ أَوْ أُخِّرَ إِلَّا قَالَ «لَا حَرَجَ» قَالَ عَبْد اللَّهِ «أَنَا أَقُولُ بِهَذَا وَأَهْلُ الْكُوفَةِ يُشَدِّدُونَ»
