Is the Hadith: "The sleep of the fasting person is an act of worship" authentic?

The Hadith "The sleep of a fasting person is worship, and his silence is glorification, and his supplication is answered, and his deeds are multiplied" is not authentic and has not been proven to be from the Prophet, peace and blessings be upon him. Its chain of narration has been weakened by Al-Bayhaqi and others, who mentioned that one of its narrators, "Sulayman Al-Nakha'i," was among the liars. It is obligatory to verify before attributing any Hadith to the Prophet, peace and blessings be upon him, due to his saying: "Whoever lies about me intentionally, let him take his seat in the Hellfire."
