What is the authenticity of the narration that tells of Sa'id ibn Zayd's dream about the Day of Resurrection, his entry into Paradise, his vision of the Houris, and his marriage to "Al-Aynā' Al-Mardiyyah (The Pleasing-Eyed One)"?

This report is baseless, and the statement of some virtuous individuals that Sa'id ibn Zayd (may Allah be pleased with him) was martyred in the Battle of Qadisiyyah after a dream is incorrect. Sa'id ibn Zayd lived until the time of Mu'awiyah and passed away in Al-Aqiq near Medina in the year 50, 51, or 52 AH. His illness and death are mentioned in Sahih al-Bukhari.
