Sahih Muslim , Hadith 2146

'Urwa b. Zubair and Fatima daughter of Mandhir b. Zubair, reported that Asma' daughter of Abu Bakr was at the time of migration in the family way with 'Abdullah b. Zubair (in her womb). She came to Quba' and gave birth to 'Abdullah at that place and then sent him to Allah's Messenger so that he should rub his palate with chewed dates. Allah's Messenger (may peace he upon him) took hold of him (the child) and he placed him in his lap and then called for dates. 'A'isha said: Some time was spent before we were able to find them. He (the Holy Prophet) chewed them and then put his saliva in his mouth. The first thing that entered his stomach, was the saliva of Allah's Messenger. Asma' said: He then rubbed him and blessed him and gave him the name of Abdullah. He ('Abdullah) went to him (the Holy Prophet) when he had attained the age of seven or eight years in order to pledge allegiance to Allah's Messenger as Zubair had commanded him to do. Allah's Messenger smiled when he saw him coming towards him and then accepted his allegiance.

حَدَّثَنَا الْحَكَمُ بْنُ مُوسَى أَبُو صَالِحٍ، حَدَّثَنَا شُعَيْبٌ، - يَعْنِي ابْنَ إِسْحَاقَ - أَخْبَرَنِي هِشَامُ بْنُ عُرْوَةَ، حَدَّثَنِي عُرْوَةُ بْنُ الزُّبَيْرِ، وَفَاطِمَةُ بِنْتُ الْمُنْذِرِ بْنِ الزُّبَيْرِ، أَنَّهُمَا قَالاَ خَرَجَتْ أَسْمَاءُ بِنْتُ أَبِي بَكْرٍ حِينَ هَاجَرَتْ وَهِيَ حُبْلَى بِعَبْدِ اللَّهِ بْنِ الزُّبَيْرِ فَقَدِمَتْ قُبَاءً فَنُفِسَتْ بِعَبْدِ اللَّهِ بِقُبَاءٍ ثُمَّ خَرَجَتْ حِينَ نُفِسَتْ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم لِيُحَنِّكَهُ فَأَخَذَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم مِنْهَا فَوَضَعَهُ فِي حَجْرِهِ ثُمَّ دَعَا بِتَمْرَةٍ قَالَ قَالَتْ عَائِشَةُ فَمَكَثْنَا سَاعَةً نَلْتَمِسُهَا قَبْلَ أَنْ نَجِدَهَا فَمَضَغَهَا ثُمَّ بَصَقَهَا فِي فِيهِ فَإِنَّ أَوَّلَ شَىْءٍ دَخَلَ بَطْنَهُ لَرِيقُ رَسُولِ اللَّهِ صلى الله عليه وسلم ثُمَّ قَالَتْ أَسْمَاءُ ثُمَّ مَسَحَهُ وَصَلَّى عَلَيْهِ وَسَمَّاهُ عَبْدَ اللَّهِ ثُمَّ جَاءَ وَهُوَ ابْنُ سَبْعِ سِنِينَ أَوْ ثَمَانٍ لِيُبَايِعَ رَسُولَ اللَّهِ صلى الله عليه وسلم وَأَمَرَهُ بِذَلِكَ الزُّبَيْرُ فَتَبَسَّمَ رَسُولُ اللَّهِ صلى الله عليه وسلم حِينَ رَآهُ مُقْبِلاً إِلَيْهِ ثُمَّ بَايَعَهُ ‏.‏

Asma' reported that she had become pregnant at Mecca with Abdullah b. Zubair (in her womt) and she (further) said: I set out (for migration to Medina) as I was in the advanced stage of pregnancy. I came to Medina and got down at the place known as Quba' and gave birth to a child there. Then I came to Allah's Messenger (may peace he upon him). He placed him (the child) in his lap and then commanded for the dates to be brought. He chewed them and then put the saliva in his mouth. The first thing which went into his stomach was the saliva of Allah's Messenger. He then rubbed his palate with dates and then invoked blessings for him and blessed him. He was the first child who was born in Islam (after Migration).

حَدَّثَنَا أَبُو كُرَيْبٍ، مُحَمَّدُ بْنُ الْعَلاَءِ حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ أَسْمَاءَ، أَنَّهَا حَمَلَتْ بِعَبْدِ اللَّهِ بْنِ الزُّبَيْرِ بِمَكَّةَ قَالَتْ فَخَرَجْتُ وَأَنَا مُتِمٌّ، فَأَتَيْتُ الْمَدِينَةَ فَنَزَلْتُ بِقُبَاءٍ فَوَلَدْتُهُ بِقُبَاءٍ ثُمَّ أَتَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فَوَضَعَهُ فِي حَجْرِهِ ثُمَّ دَعَا بِتَمْرَةٍ فَمَضَغَهَا ثُمَّ تَفَلَ فِي فِيهِ فَكَانَ أَوَّلَ شَىْءٍ دَخَلَ جَوْفَهُ رِيقُ رَسُولِ اللَّهِ صلى الله عليه وسلم ثُمَّ حَنَّكَهُ بِالتَّمْرَةِ ثُمَّ دَعَا لَهُ وَبَرَّكَ عَلَيْهِ وَكَانَ أَوَّلَ مَوْلُودٍ وُلِدَ فِي الإِسْلاَمِ ‏.‏

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ، عَنْ عَلِيِّ بْنِ مُسْهِرٍ، عَنْ هِشَامِ، بْنِ عُرْوَةَ عَنْ أَبِيهِ، عَنْ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ، أَنَّهَا هَاجَرَتْ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم وَهِيَ حُبْلَى بِعَبْدِ اللَّهِ بْنِ الزُّبَيْرِ ‏.‏ فَذَكَرَ نَحْوَ حَدِيثِ أَبِي أُسَامَةَ ‏.‏
