Did Adam and the Messenger, may Allah bless him and grant him peace, not enter Paradise, even though it is described as that "which no eye has seen nor ear has heard"?

Paradise contains what no eye has seen, no ear has heard, and no human heart has conceived. Adam, peace be upon him, was in the Eternal Paradise, and the Prophet, peace and blessings be upon him, saw Paradise and entered it. The apparent contradiction between this and the Hadith is resolved by understanding that what has been prepared for the righteous is that which no eye has seen, no ear has heard, and no human heart has conceived. As for the رؤية (seeing) of the Prophets, it was of some of what is in Paradise. Thus, there is that which no one has seen, and there is that which some eyes have seen. This is corroborated by the Hadith about the lowest and highest in rank among the people of Paradise.
