'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.
