Zainab's original name was "Barrah," but it was said' "By that she is giving herself the prestige of piety." So the Prophet ﷺ changed her name to Zainab.  

أَنَّ زَيْنَبَ كَانَ اسْمُهَا بَرَّةَ فَقِيلَ تُزَكِّي نَفْسَهَا فَسَمَّاهَا رَسُولُ اللَّهِ ﷺ زَيْنَبَ  

"Zainab used to be called "Barrah" (good), and it was said that she was praising herself. So the Messenger of Allah ﷺ changed her name to Zainab."  

أَنَّ زَيْنَبَ كَانَ اسْمُهَا بَرَّةَ فَقِيلَ لَهَا تُزَكِّي نَفْسَهَا فَسَمَّاهَا رَسُولُ اللَّهِ ﷺ زَيْنَبَ
