Asma bint Abu Bakr set out when she emigrated while she was pregnant with Abdullah bin Zubayr. She arrived at Quba and gave birth to Abdullah there. After giving birth, she took him to the Messenger of Allah ﷺ so that he could perform tahnik on him. The Messenger of Allah ﷺ took the child from her and placed him in his lap, then he called for a date.Ayesha said, "We spent some time searching for it before we found one."He chewed the date and then placed it in the child's mouth, so the first thing to enter his stomach was the saliva of the Messenger of Allah ﷺ.Asma then said, "He then wiped him, prayed for him, and named him Abdullah. Later, when he was seven or eight years old, he came to give his pledge of allegiance to the Messenger of Allah ﷺ, as Zubayr had instructed him to do. The Messenger of Allah ﷺ smiled when he saw him approaching, and then accepted his pledge."
حدثنا الحكم بن موسى أبو صالح حدثنا شعيب يعني ابن إسحق أخبرني هشام بن عروة
خرجت أسماء بنت أبي بكر حين هاجرت وهي حبلى بعبد الله بن الزبير فقدمت قباء فنفست بعبد الله بقباء ثم خرجت حين نفست إلى رسول الله ﷺ ليحنكه فأخذه رسول الله ﷺ منها فوضعه في حجره ثم دعا بتمرة قال قالت عائشة فمكثنا ساعة نلتمسها قبل أن نجدها فمضغها ثم بصقها في فيه فإن أول شيء دخل بطنه لريق رسول الله ﷺ ثم قالت أسماء ثم مسحه وصلى عليه وسماه عبد الله ثم جاء وهو ابن سبع سنين أو ثمان ليبايع رسول الله ﷺ وأمره بذلك الزبير فتبسم رسول الله ﷺ حين رآه مقبلا إليه ثم بايعه
