Anas bin Malik said “I brought my brother when he was born to Prophet ﷺ to chew something for him and rub his palate with it and found him in a sheep pen branding the sheep, I think, on their ears.”
أَتَيْتُ النَّبِيَّ ﷺ بِأَخٍ لِي حِينَ وُلِدَ لِيُحَنِّكَهُ فَإِذَا هُوَ فِي مِرْبَدٍ يَسِمُ غَنَمًا أَحْسِبُهُ قَالَ فِي آذَانِهَا
I brought a brother of mine to the Prophet ﷺ to do Tahnik for him while the Prophet ﷺ was in a sheep fold of his, and I saw him branding a sheep. (The sub-narrator said: I think Anas said, branding it on the ear.)
دَخَلْتُ عَلَى النَّبِيِّ ﷺ بِأَخٍ لِي يُحَنِّكُهُ وَهْوَ فِي مِرْبَدٍ لَهُ فَرَأَيْتُهُ يَسِمُ شَاةً حَسِبْتُهُ قَالَ فِي آذَانِهَا
[Machine] I came to the Prophet ﷺ with my brother to have him circumcised. He said, "I saw that he had a thick beard, I thought he may give him a nickname."
أَتَيْتُ النَّبِيَّ ﷺ بِأَخٍ لِي لِيُحَنِّكَهُ فِي الْمِرْبَدِ قَالَ فَرَأَيْتُهُ يَسِمُ شِيَاهًا أَحْسَبُهُ قَالَ فِي آذَانِهَا
