Hadith 43:179
Anas said; I took ‘Abd Allah b. Abi Talhah, when he was born, to the Prophet (May peace be upon him), and the prophet (May peace be upon him) 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 (May peace be upon him) 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 صلى الله عليه وسلم حِينَ وُلِدَ وَالنَّبِيُّ صلى الله عليه وسلم 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 صلى الله عليه وسلم " حِبُّ الأَنْصَارِ التَّمْرُ " . وَسَمَّاهُ عَبْدَ اللَّهِ
