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.”
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ هِشَامِ بْنِ زَيْدٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ أَتَيْتُ النَّبِيَّ صلى الله عليه وسلم بِأَخٍ لِي حِينَ وُلِدَ لِيُحَنِّكَهُ فَإِذَا هُوَ فِي مِرْبَدٍ يَسِمُ غَنَمًا - أَحْسِبُهُ قَالَ - فِي آذَانِهَا .
