We never called Zayd bin Haritha anything but Zayd bin Muhammad, until this was revealed in the Quran, "Call them by the names of their fathers, that is more just in the sight of Allah" [Ahzab 33:5].
ما كنا ندعو زيد بن حارثة إلا زيد بن محمد حتى نزل في القرآن: {أدعوهم لآبائهم هو أقسط عند الله} [الأحزاب: ٥].
