حَدَّثَنَا أَبُو بَکْرٍ حَدَّثَنَا غُنْدَرٌ عَنْ شُعْبَةَ عَنْ عَطَائِ بْنِ أَبِي مَيْمُونَةَ قَالَ سَمِعْتُ أَبَا رَافِعٍ يُحَدِّثُ عَنْ أَبِي هُرَيْرَةَ أَنَّ زَيْنَبَ کَانَ اسْمُهَا بَرَّةَ فَقِيلَ لَهَا تُزَکِّي نَفْسَهَا فَسَمَّاهَا رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ زَيْنَبَ
ابن ماجہ · Hadith 3732
It was narrated from Abu Hurairah that Zainab used to be called "Barrah" (good), and it was said that she was praising herself. So the Messenger of Allah(saw) changed her name to Zainab.(Sahih)
