Anas b. Malik (Allah be pleased wish him) reported that Messenger of Allah ﷺ came to Mina; he went to the Jamra and threw pebbles at it, after which he went to his lodging in Mina, and sacrificed the animal. He then called for a barber and, turning his right side to him, let him shave him; after which he tiimed his left side. He then gave (these hair) to the people. (Using translation from Muslim 1305a)   

أَنَّ رَسُولَ اللهِ ﷺ أَتَى مِنًى فَأَتَى الْجَمْرَةَ فَرَمَاهَا ثُمَّ أَتَى مَنْزِلَهُ بِمِنًى وَنَحَرَ ثُمَّ قَالَ لِلْحَلَّاقِ خُذْ وَأَشَارَ إِلَى جَانِبِهِ الْأَيْمَنِ ثُمَّ الْأَيْسَرِ ثُمَّ جَعَلَ يُعْطِيهِ النَّاسَ  

[Machine] Abu al-Abbas al-Asamm reported that al-Rabi' informed al-Shafi'i, who informed Sulayman, who reported from 'Amr ibn Dinar, who said: A barber told me that he trimmed the hair of Ibn 'Abbas, so he said: Start with the right side.  

ثنا أَبُو الْعَبَّاسِ الْأَصَمُّ أنبأ الرَّبِيعُ أنبأ الشَّافِعِيُّ أنبأ سُلَيْمَانُ عَنْ عَمْرِو بْنِ دِينَارٍ قَالَ أَخْبَرَنِي حَجَّامٌ أَنَّهُ قَصَّرَ ابْنَ عَبَّاسٍ فَقَالَ ابْدَأْ بِالشِّقِّ الْأَيْمَنِ
