Can a person reach the degree of receiving revelation directly from Allah
while they are neither a prophet nor a messenger?
No human can receive revelation directly from Allah whether news or legislation except the prophets and messengers (peace be upon them), else it will be a true vision which is only seen by a pious person or someone sees it about another during sleep. It is part of forty six parts of revelation. As for true insight, it is a kind of inspiration like
`Umar ibn Al-Khattab (may Allah be pleased with him) was. However, nightly visions and insight which were given to people other than prophets (peace be upon them) are not considered a basis of legislation and should not be taken for granted. Dreams and insight are mixed up with true and false ones. So they are not dependable except if they are seen by messengers and prophets (peace be upon them). Therefore, the Prophet (peace be upon him) did not depend upon them even if they were of
`Umar (may Allah be pleased with him), but he depended on what has been received from revelation.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
