ذِكْرُ الْعِلَّةِ الَّتِي مِنْ أَجْلِهَا كَانَ يُغَيِّرُ ﷺ هَذَا الْجِنْسَ مِنَ الْأَسْمَاءِ
"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." (Using translation from Ibn Mājah 3732)
«كَانَ اسْمُ زَيْنَبَ بَرَّةَ فَقَالُوا تُزَكِّي نَفْسَهَا فَسَمَّاهَا رَسُولُ اللَّهِ ﷺ زَيْنَبَ»
