'Urwa bin Zubair and Fatima daughter of Mandhir bin Zubair, reported that Asma' daughter of Abu Bakr (RA) was at the time of migration in the family way with 'Abdullah bin Zubair (in her womb). She came to Quba' and gave birth to 'Abdullah at that place and then sent him to Allah's Messenger ( صلی اللہ علیہ وسلم ) 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 ( صلی اللہ علیہ وسلم ) . 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 ( صلی اللہ علیہ وسلم ) as Zubair had commanded him to do. Allah's Messenger ( صلی اللہ علیہ وسلم ) smiled when he saw him coming towards him and then accepted his allegiance.

Asma' reported that she had become pregnant at Makkah with'Abdullah bin Zubair (in her womb) and she (further) said: I set out (for migration to Madinah) as I was in the advanced stage of pregnancy. I came to Madinah 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 ( صلی اللہ علیہ وسلم ) . 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).

Asma', daughter of Abu Bakr, reported that when she migrated to Allah's Messenger ( صلی اللہ علیہ وسلم ) in Medina she was in the family way with Abdullah b. Zubair in her womb.
