Asma’ daughter of Abu Bakr said she conceived ‘Abdallah b. azZubair in Mecca and gave birth to him in Quba’, then took him to Allah's Messenger ﷺ and placed him in his lap. He called for a date, chewed it and spat in his mouth, after which he rubbed his palate and then made supplication for him and invoked a blessing on him. He was the first child to be born in the Islamic period. (Bukhari and Muslim.)
وَعَنْ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ أَنَّهَا حَمَلَتْ بِعَبْدِ اللَّهِ بْنِ الزُّبَيْرِ بِمَكَّةَ قَالَتْ: فَوَلَدْتُ بِقُبَاءَ ثُمَّ أَتَيْتُ بِهِ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَوَضَعْتُهُ فِي حِجْرِهِ ثُمَّ دَعَا بِتَمْرَةٍ فَمَضَغَهَا ثُمَّ تَفَلَ فِي فِيهِ ثُمَّ حَنَّكَهُ ثُمَّ دَعَا لَهُ وبرك عَلَيْهِ فَكَانَ أَوَّلَ مَوْلُودٍ وُلِدَ فِي الْإِسْلَامِ
