Ibn Jurayj (may Allah have mercy on him) said concerning the verse "And you concealed within yourself what Allah was to disclose" [al-Ahzab: 37]: "In the heart of the Messenger of Allah (peace and blessings be upon him) was his wish that Zayd would divorce her and that he (peace and blessings be upon him) would marry her, so Allah willed nothing but to disclose what the Prophet (peace and blessings be upon him) had concealed within himself."
