How many children did Abu bakr have before he died?

All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.

The children of Abu Bakr As-Siddeeq whom he left behind after he died were five; two sons: Abdur-Rahmaan and Muhammad; and three daughters: ‘Aa’ishah, Asma’ and Umm Kulthoom, may Allah be pleased with all the Companions.

This was mentioned by Ibn Qutaybah in his book Al-Ma’arif.

Allah knows best.
