Anas said; I took ‘Abd Allah b. Abi Talhah, when he was born, to the Prophet ﷺ, and the prophet ﷺ was wearing a wool;en cloak and rubbing tar on his camel. He asked:

Have you some dates? I said : Yes. I then gave him some dates which he put in his mouth, chewed them, opened his mouth and them in it. The baby began to lick them. The prophet ﷺ said: ANSAR’s favourite (fruit) is dates. And he gave him the name of ‘Abd al-Rahman.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، قَالَ ذَهَبْتُ بِعَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ إِلَى النَّبِيِّ ﷺ حِينَ وُلِدَ وَالنَّبِيُّ ﷺ فِي عَبَاءَةٍ يَهْنَأُ بَعِيرًا لَهُ قَالَ " هَلْ مَعَكَ تَمْرٌ " . قُلْتُ نَعَمْ - قَالَ - فَنَاوَلْتُهُ تَمَرَاتٍ فَأَلْقَاهُنَّ فِي فِيهِ فَلاَكَهُنَّ ثُمَّ فَغَرَ فَاهُ فَأَوْجَرَهُنَّ إِيَّاهُ فَجَعَلَ الصَّبِيُّ يَتَلَمَّظُ فَقَالَ النَّبِيُّ ﷺ " حِبُّ الأَنْصَارِ التَّمْرُ " . وَسَمَّاهُ عَبْدَ اللَّهِ .
