حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ ، حَدَّثَنَا الْوَلِيدُ ، حَدَّثَنَا أَبُو عَمْرٍو الْأَوْزَاعِيُّ ، حَدَّثَنِي إِسْحَاقُ بْنُ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ ، حَدَّثَنِي أَنَسُ بْنُ مَالِكٍرَضِيَ اللَّهُ عَنْهُ , قَالَ : " غَدَوْتُ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِعَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ لِيُحَنِّكَهُ ، فَوَافَيْتُهُ فِي يَدِهِ الْمِيسَمُ يَسِمُ إِبِلَ الصَّدَقَةِ " .
Narrated Anas bin Malik: I took `Abdullah bin Abu Talha to Allah's Apostle to perform Tahnik for him. (Tahnik was a custom among the Muslims that whenever a child was born they used to take it to the Prophet who would chew a piece of date and put a part of its juice in the child's mouth). I saw the Prophet and he had an instrument for branding in his hands and was branding the camels of Zakat.
