Could the Prophet, peace and blessings be upon him, speak English if a Muslim saw him in a dream?

A Muslim's vision of the Prophet, peace and blessings be upon him, in a dream is considered true if he sees him in his established form and descriptions. So, whoever sees him in that manner has truly seen him. If one sees him speaking a language other than Arabic, yet his descriptions match his established descriptions, then the vision is truthful and this does not invalidate its authenticity. This is because restricting the truthfulness of the vision to hearing his words only in Arabic would limit this honor to certain people over others. As for his words, peace and blessings be upon him, in a dream, they are not like his words in wakefulness, and may require interpretation and expression that differs from their visible form.
