Al-Adab Al-Mufrad 1254
Anas said, "On the day he was born, I took 'Abdullah ibn Abi Talha to the Prophet, may Allah bless him and grant him peace. I found him wearing a woollen robe while he was marking one of his camels with tar. The Prophet said, 'Do you have any dates with you?' 'Yes,' I replied. I gave him some dates. He chewed the dates and opened the child's mouth and put some chewed dates into the child's mouth. The child licked his lips. The Prophet ﷺ said, 'The Ansar love dates,' and gave him the name 'Abdullah."
حَدَّثَنَا حَجَّاجُ بْنُ مِنْهَالٍ، قَالَ: حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ قَالَ: ذَهَبْتُ بِعَبْدِ اللهِ بْنِ أَبِي طَلْحَةَ إِلَى النَّبِيِّ ﷺ يَوْمَ وُلِدَ، وَالنَّبِيُّ ﷺ فِي عَبَاءَةٍ يَهْنَأُ بَعِيرًا لَهُ، فَقَالَ: مَعَكَ تَمَرَاتٌ؟ قُلْتُ: نَعَمْ، فَنَاوَلْتُهُ تَمَرَاتٍ فَلاَكَهُنَّ، ثُمَّ فَغَرَ فَا الصَّبِيِّ، وَأَوْجَرَهُنَّ إِيَّاهُ، فَتَلَمَّظَ الصَّبِيُّ، فَقَالَ النَّبِيُّ ﷺ: حُبَّ الأَنْصَارِ التَّمْرَ، وَسَمَّاهُ: عَبْدَ اللهِ.
