Chapter 39: The Book of Manners and Etiquette
Muhammad b. 'Amr b. 'Ata' reported: I had given the name Barra to my daughter. Zainab, daughter of Abu Salama, told me that Allah' s' Messenger (ﷺ) had forbidden me to give this name. (She said): I was also called Barra, but Allah' s Messenger (ﷺ) said: Don' t hold yourself to be pious. It is God alone who knows the people of piety among you. They (the Companions) said: Then, what name should we give to her? He said: Name her as Zainab.
