Sahih al-Bukhari 5470
Narrated Anas bin Malik:
Abu Talha had a child who was sick. Once, while Abu Talha was out, the
     child died. When Abu Talha returned home, he asked, "How does my son 
     fare?" Um Salaim (his wife) replied, "He is quieter than he has ever 
     been." Then she brought supper for him and he took his supper and 
     slept with her. When he had finished, she said (to him), "Bury the 
     child (as he's dead)." Next morning Abu Talha came to Allah's Messenger (ﷺ) 
     and told him about that. The Prophet (ﷺ) said (to him), "Did you sleep 
     with your wife last night?" Abu Talha said, "Yes". The Prophet (ﷺ) said, 
     "O Allah! Bestow your blessing on them as regards that night of 
     theirs." Um Sulaim gave birth to a boy. Abu Talha told me to take care
     of the child till it was taken to the Prophet. Then Abu Talha took the
     child to the Prophet (ﷺ) and Um Sulaim sent some dates along with the 
     child. The Prophet (ﷺ) took the child (on his lap) and asked if there was 
     something with him. The people replied, "Yes, a few dates." The 
     Prophet took a date, chewed it, took some of it out of his mouth, put 
     it into the child's mouth and did Tahnik for him with that, and named 
     him 'Abdullah.
حَدَّثَنَا مَطَرُ بْنُ الْفَضْلِ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ عَوْنٍ، عَنْ أَنَسِ بْنِ سِيرِينَ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ كَانَ ابْنٌ لأَبِي طَلْحَةَ يَشْتَكِي، فَخَرَجَ أَبُو طَلْحَةَ، فَقُبِضَ الصَّبِيُّ فَلَمَّا رَجَعَ أَبُو طَلْحَةَ قَالَ مَا فَعَلَ ابْنِي قَالَتْ أُمُّ سُلَيْمٍ هُوَ أَسْكَنُ مَا كَانَ‏.‏ فَقَرَّبَتْ إِلَيْهِ الْعَشَاءَ فَتَعَشَّى، ثُمَّ أَصَابَ مِنْهَا، فَلَمَّا فَرَغَ قَالَتْ وَارِ الصَّبِيَّ‏.‏ فَلَمَّا أَصْبَحَ أَبُو طَلْحَةَ أَتَى رَسُولَ اللَّهِ صلى الله عليه وسلم فَأَخْبَرَهُ فَقَالَ ‏"‏ أَعْرَسْتُمُ اللَّيْلَةَ ‏"‏‏.‏ قَالَ نَعَمْ‏.‏ قَالَ ‏"‏ اللَّهُمَّ بَارِكْ لَهُمَا ‏"‏‏.‏ فَوَلَدَتْ غُلاَمًا قَالَ لِي أَبُو طَلْحَةَ احْفَظْهُ حَتَّى تَأْتِيَ بِهِ النَّبِيَّ صلى الله عليه وسلم فَأَتَى بِهِ النَّبِيَّ صلى الله عليه وسلم وَأَرْسَلَتْ مَعَهُ بِتَمَرَاتٍ، فَأَخَذَهُ النَّبِيُّ صلى الله عليه وسلم فَقَالَ ‏"‏ أَمَعَهُ شَىْءٌ ‏"‏‏.‏ قَالُوا نَعَمْ تَمَرَاتٌ‏.‏ فَأَخَذَهَا النَّبِيُّ صلى الله عليه وسلم فَمَضَغَهَا، ثُمَّ أَخَذَ مِنْ فِيهِ فَجَعَلَهَا فِي فِي الصَّبِيِّ، وَحَنَّكَهُ بِهِ، وَسَمَّاهُ عَبْدَ اللَّهِ‏.‏
