While the Prophet ﷺ was delivering a sermon on the Day of Nahr (i.e., 10th Dhul-Hijja-Day of slaughtering the sacrifice), a man got up saying, "I thought, O Messenger of Allah ﷺ, such-and-such a thing was to be done before such-and-such a thing." Another man got up, saying, "O Messenger of Allah ﷺ! As regards these three (acts of Hajj), thought so-and-so." The Prophet ﷺ said, "Do, and there is no harm," concerning all those matters on that day. And so, on that day, whatever question he was asked, he said, "Do it, do it, and there is no harm therein."  

البخاري:٦٦٦٥حَدَّثَنَا عُثْمَانُ بْنُ الْهَيْثَمِ أَوْ مُحَمَّدٌ عَنْهُ عَنِ ابْنِ جُرَيْجٍ قَالَ سَمِعْتُ ابْنَ شِهَابٍ يَقُولُ حَدَّثَنِي عِيسَى بْنُ طَلْحَةَ أَنَّ عَبْدَ اللَّهِ بْنَ عَمْرِو بْنِ الْعَاصِ حَدَّثَهُ

أَنَّ النَّبِيَّ ﷺ بَيْنَمَا هُوَ يَخْطُبُ يَوْمَ النَّحْرِ إِذْ قَامَ إِلَيْهِ رَجُلٌ فَقَالَ كُنْتُ أَحْسِبُ يَا رَسُولَ اللَّهِ كَذَا وَكَذَا قَبْلَ كَذَا وَكَذَا ثُمَّ قَامَ آخَرُ فَقَالَ يَا رَسُولَ اللَّهِ كُنْتُ أَحْسِبُ كَذَا وَكَذَا لِهَؤُلاَءِ الثَّلاَثِ فَقَالَ النَّبِيُّ ﷺ افْعَلْ وَلاَ حَرَجَ لَهُنَّ كُلِّهِنَّ يَوْمَئِذٍ فَمَا سُئِلَ يَوْمَئِذٍ عَنْ شَىْءٍ إِلاَّ قَالَ افْعَلْ وَلاَ حَرَجَ

I witnessed the Prophet ﷺ when he was delivering the sermon on the Day of Nahr. A man stood up and said, "I thought that such and such was to be done before such and such. I got my hair shaved before slaughtering." (Another said), "I slaughtered the Hadi before doing the Rami." So, the people asked about many similar things. The Prophet ﷺ said, "Do it (now) and there is no harm in all these cases." Whenever the Prophet ﷺ was asked about anything on that day, he replied, "Do it (now) and there is no harm in it."

أَنَّهُ شَهِدَ النَّبِيَّ ﷺ يَخْطُبُ يَوْمَ النَّحْرِ فَقَامَ إِلَيْهِ رَجُلٌ فَقَالَ كُنْتُ أَحْسِبُ أَنَّ كَذَا قَبْلَ كَذَا ثُمَّ قَامَ آخَرُ فَقَالَ كُنْتُ أَحْسِبُ أَنَّ كَذَا قَبْلَ كَذَا حَلَقْتُ قَبْلَ أَنْ أَنْحَرَ نَحَرْتُ قَبْلَ أَنْ أَرْمِيَ وَأَشْبَاهَ ذَلِكَ فَقَالَ النَّبِيُّ ﷺ افْعَلْ وَلاَ حَرَجَ لَهُنَّ كُلِّهِنَّ فَمَا سُئِلَ يَوْمَئِذٍ عَنْ شَىْءٍ إِلاَّ قَالَ افْعَلْ وَلاَ حَرَجَ

As Allah's Apostle. ﷺ was delivering sermon on the Day of Nahr, a man stood up before him and said: Messenger of Allah, I did not know that such and such (rite was to be performed) before such and such (rite). Then another man came and said: Messenger of Allah, I thought that such and such (rite) should precede such and such (rite), and then another man came and said: Messenger of Allah, I had thought that such and such was before such and such, and such and such (is the sequence) of the three (rites, viz. throwing of pebbles, sacrificing of animal and shaving of one's head). He said to all these three: Do now (if you have not observed the cequence) ; there is no harm in it.  

مسلم:١٣٠٦dوَحَدَّثَنَا عَلِيُّ بْنُ خَشْرَمٍ أَخْبَرَنَا عِيسَى عَنِ ابْنِ جُرَيْجٍ قَالَ سَمِعْتُ ابْنَ شِهَابٍ يَقُولُ حَدَّثَنِي عِيسَى بْنُ طَلْحَةَ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ عَمْرِو بْنِ الْعَاصِ

أَنَّ النَّبِيَّ ﷺ بَيْنَا هُوَ يَخْطُبُ يَوْمَ النَّحْرِ فَقَامَ إِلَيْهِ رَجُلٌ فَقَالَ مَا كُنْتُ أَحْسِبُ يَا رَسُولَ اللَّهِ أَنَّ كَذَا وَكَذَا قَبْلَ كَذَا وَكَذَا ثُمَّ جَاءَ آخَرُ فَقَالَ يَا رَسُولَ اللَّهِ كُنْتُ أَحْسِبُ أَنَّ كَذَا قَبْلَ كَذَا وَكَذَا لِهَؤُلاَءِ الثَّلاَثِ قَالَ افْعَلْ وَلاَ حَرَجَ
