Is it permissible for righteous people to say to one another in this world: "If you do not see me in Paradise, then ask about me and intercede for me," knowing that intercession is exclusive to the Prophet, peace and blessings be upon him, and no one is guaranteed Paradise?

This question is frivolous and useless, and based on imagination; because the states of the Day of Judgment are unseen matters that cannot be compared to the states of this world. As for the people of Paradise seeing each other, that is neither affirmed nor denied, and its knowledge is with Allah.
