What is the degree of authenticity of the hadith "Moaning is tasbih (glorification of God)," and was it narrated from the Prophet, peace and blessings be upon him, and what are its chains of transmission?

The following tradition was mentioned by Al-Dailami in Al-Firdaws: "A sick person's sleep on his bed is worship, his fasting is 'tahlil' (utterance of 'la ilaha illa Allah'), and his moaning is 'tasbih' (utterance of 'subhan Allah')." This tradition was cited by Mulla Ali Al-Qari in Al-Mawdu'at, and Al-Asqalani stated that it is not authentic. Al-Firdaws is a source known for containing weak hadiths.
