Al-Adab Al-Mufrad, Book 53, Hadith 1254 (In-Book) ⓘ

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, may Allah bless him and grant him peace, 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 صلى الله عليه وسلم يَوْمَ وُلِدَ، وَالنَّبِيُّ صلى الله عليه وسلم فِي عَبَاءَةٍ يَهْنَأُ بَعِيرًا لَهُ، فَقَالَ‏:‏ مَعَكَ تَمَرَاتٌ‏؟‏ قُلْتُ‏:‏ نَعَمْ، فَنَاوَلْتُهُ تَمَرَاتٍ فَلاَكَهُنَّ، ثُمَّ فَغَرَ فَا الصَّبِيِّ، وَأَوْجَرَهُنَّ إِيَّاهُ، فَتَلَمَّظَ الصَّبِيُّ، فَقَالَ النَّبِيُّ صلى الله عليه وسلم‏:‏ حُبَّ الأَنْصَارِ التَّمْرَ، وَسَمَّاهُ‏:‏ عَبْدَ اللهِ‏.‏
