Does seeing the Prophet in a dream, saying: "Do not think that Aisha did not go astray; Aisha went astray and may go to Hell," mean that the vision is true, knowing that Satan cannot impersonate him?

Visions are not a legitimate source to rely on for discrediting individuals or proving them to be among the people of Hellfire. Seeing the Prophet, peace and blessings be upon him, in a dream is true, and Satan cannot impersonate him. However, what the dreamer hears in the dream must be presented to the Shari'ah (Islamic law); if it conforms to it, it is accepted, otherwise, it is rejected. It is not possible to invalidate what is established by Shari'ah based on a dream vision; scholars have unanimously agreed that a dream does not invalidate an established Sunnah (definition), nor does it establish a Sunnah that is not established, nor does it alter what has been determined in Islamic law.
