3909. Narrated Asmā' رضي الله عنها that she conceived 'Abdullāh bin Az-Zubair. She added, "I emigrated to Al-Madīna while I was at full term of pregnancy and alighted at Qubā, where I gave birth to him. Then I brought him to the Prophet ﷺ and put him on his lap. The Prophet ﷺ asked for a date-fruit, chewed it, and put some of its juice in the child's mouth. So, the first thing that entered the child's stomach was the saliva of Allāh's Messenger ﷺ. Then the Prophet ﷺ rubbed the child's palate with a date-fruit and invoked for Allāh's Blessings on him, and he was the first child born (amongst the emigrants) in the Islāmic Land (i.e., Al-Madīna)."
