It is narrated from Sayyida Asma bint Abi Bakr (may Allah be pleased with her) that she became pregnant with Abdullah bin Zubair (may Allah be pleased with him) in Mecca. She says: My term was complete when I set out on the journey of migration. I stayed at Quba and gave birth to the child there. I took him to the service of the Noble Prophet (peace and blessings be upon him) and placed him in his lap. The Prophet asked for dates, chewed them, and put them in the child’s mouth. The very first thing to enter his stomach was the saliva of the Messenger of Allah (peace and blessings be upon him). In this way, the Prophet (peace and blessings be upon him) gave him the tahneek of dates and prayed for blessings for him. He was the first child to be born in Islam.
