The First Child Born in Islam

Who was the first newborn in Madīnah? Asmāʾ bint Abī Bakr (may Allah be pleased with her) says: "When I emigrated, I was pregnant. When I came to Madīnah, I stayed in Qubāʾ and gave birth there to him, ʿAbdullāh ibn al-Zubayr." She then took him to the Messenger of Allah (peace be upon him) and placed the newborn in his lap. The Messenger of Allah (peace be upon him) called for a date, which he chewed, and then he placed the date, the chewed paste, in the mouth of ʿAbdullāh ibn al-Zubayr, so that the first thing that entered the baby's stomach was from the mouth of the Messenger of Allah (peace be upon him). And then he prayed for him and blessed him. She says he was the first baby born in Islam, and this is in al-Bukhārī. Notice here: she said, not the first baby born in Madīnah, but the first baby born in Islam. The Companions considered that the beginning of Islam was in Madīnah, because that was the beginning of the Islamic state, as if the whole period of thirteen years in Makkah had been a preparation for it. So she did not say the first child born after the hijrah, or the first child born in Madīnah — this was the first child born in Islam. Islam only became complete when the Muslims lived as a Muslim society, in a Muslim state ruled by the law of Allah (swt). So this tells us that we are missing a lot.
