The Messenger of Allah ﷺ threw pebbles at the last jamrah (Jamrat al-'Aqabah) on the day of sacrifice. He then returned to his lodging at Mina. He called for a sacrificial animal which he slaughtered. He then called for a barber. He held the right side of his head and shaved it. He then began to distribute among those who were around him one or two hair each. He then held the left side of his head and shaved it. Again he said: Is Abu Talhah here ? He then gave it (the hair shaved off) to Abu Talhah. (Using translation from Abū Dāʾūd 1981)   

أَنَّ رَسُولَ اللهِ ﷺ رَمَى جَمْرَةَ الْعَقَبَةِ يَوْمَ النَّحْرِ ثُمَّ رَجَعَ إِلَى مَنْزِلِهِ بِمِنًى فَدَعَا بِذِبْحٍ فَذُبِحَ ثُمَّ دَعَا بِالْحَلَّاقِ فَأَخَذَ شِقَّ رَأْسِهِ الْأَيْمَنَ فَحَلَقَهُ فَجَعَلَ يَقْسِمُ بَيْنَ مَنْ يَلِيهِ الشَّعْرَةَ وَالشَّعَرَتَيْنِ ثُمَّ أَخَذَ شِقَّ رَأْسِهِ الْأَيْسَرَ فَحَلَقَهُ ثُمَّ قَالَ هَاهُنَا أَبُو طَلْحَةَ؟ فَدَفَعَهُ إِلَى أَبِي طَلْحَةَ  

[Machine] When the Messenger of Allah ﷺ shaved his head on the day of sacrifice, he took his hair in his right hand. When the barber shaved the right side of his head, the Messenger of Allah ﷺ said, "O Anas, take this [hair] to Abu Talha and Umm Sulaim." When the people saw what he had done with it, they rushed to collect the remaining hair. This person took a lock, that person took strands, and another person took something else. Muhammad said, "I narrated this hadith to 'Ubaidullah al-Salmani, and he said, 'I would rather have a single hair from it than all the yellow and white [hairs] on the face of the earth and in its belly.'"  

فَلَمَّا حَلَقَ رَسُولُ اللهِ ﷺ يَوْمَ النَّحْرِ قَبَضَ شَعْرَهُ بِيَدِهِ الْيُمْنَى فَلَمَّا حَلَقَ الْحَلَّاقُ شِقَّ رَأْسِهِ الْأَيْمَنَ قَالَ رَسُولُ اللهِ ﷺ يَا أَنَسُ انْطَلِقْ بِهَذَا إِلَى أَبِي طَلْحَةَ وَأُمِّ سُلَيْمٍ قَالَ فَلَمَّا رَأَى النَّاسُ مَا خَصَّهُ بِهِ مِنْ ذَلِكَ تَنَافَسُوا فِي بَقِيَّةِ شَعْرِهِ فَهَذَا يَأْخُذُ الْخُصْلَةَ وَهَذَا يَأْخُذُ الشَّعَرَاتِ وَهَذَا يَأْخُذُ الشَّيْءَ قَالَ مُحَمَّدٌ فَحَدَّثْتُ الْحَدِيثَ عُبَيْدِ اللهِ السَّلْمَانِيِّ فَقَالَ لَأَنْ تَكُونَ عِنْدِي مِنْهُ شَعْرَةٌ أَحَبُّ إِلَيَّ مِنْ كُلِّ أَصْفَرَ وَأَبْيَضَ أَصْبَحَ عَلَى وَجْهِ الْأَرْضِ وَفِي بَطْنِهَا
