Sahih Muslim , Book 25, Hadith 5337 (USC-MSA) ⓘ

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 had forbidden me to give this name. (She said): I was also called Barra, but Allah's Messenger 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.

حَدَّثَنَا عَمْرٌو النَّاقِدُ، حَدَّثَنَا هَاشِمُ بْنُ الْقَاسِمِ، حَدَّثَنَا اللَّيْثُ، عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ، عَنْ مُحَمَّدِ بْنِ عَمْرِو بْنِ عَطَاءٍ، قَالَ سَمَّيْتُ ابْنَتِي بَرَّةَ فَقَالَتْ لِي زَيْنَبُ بِنْتُ أَبِي سَلَمَةَ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ هَذَا الاِسْمِ وَسُمِّيتُ بَرَّةَ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ لاَ تُزَكُّوا أَنْفُسَكُمُ اللَّهُ أَعْلَمُ بِأَهْلِ الْبِرِّ مِنْكُمْ ‏"‏ ‏.‏ فَقَالُوا بِمَ نُسَمِّيهَا قَالَ ‏"‏ سَمُّوهَا زَيْنَبَ ‏"‏ ‏.‏
