"We called Zaid bin Harithah nothing but 'Zaid bin Muhammad' until the Qur'an was revealed (ordering): Call them by their fathers, that is more just according to Allah. (33:5)"
مَا كُنَّا نَدْعُو زَيْدَ بْنَ حَارِثَةَ إِلاَّ زَيْدَ بْنَ مُحَمَّدٍ حَتَّى نَزَلَتْ ( ادعُوهُمْ لِأَبَائِهِمْ هُوَ أَقْسَطُ عِنْدَ اللَّهِ ) هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
