Narrated Asmâ' that she conceived 'Abdullâh bin Az-Zubair. She added, "I migrated to Al-Madina while I was at full term of pregnancy and alighted at Qubâ'where I gave birth to him. Then I brought him to the Prophet (ﷺ) and put him in his lap. The Prophet (ﷺ) asked for a date, 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 Allâh's Messenger (ﷺ). Then the Prophet (ﷺ) rubbed the child's palate with a date and invoked for Allâh's Blessings on him, and he was the first child born (amongst the emigrants) in the Islâmic land (i.e. Al-Madina).
