Is the Hadith that mentions that when a man enters upon his wife in Paradise, he prostrates to her, thinking she is Allah, whereupon she says to him: "Rather, I am your wife from the worldly life," authentic?

This statement is not a hadith; rather, it is false. Believers will see their Lord in the gathering places (on the Day of Judgment) and in Paradise, as is the creed of Ahl al-Sunnah wa al-Jama'ah (the People of the Sunnah and the Community). Al-Bukhari and Muslim narrated that people will see their Lord on the Day of Resurrection and will recognize Him, and likewise they will see Him in Paradise. This refutes the claim that a believer will prostrate to his wife from among the houris, thinking she is Allah.
