The Authenticity of the Hadith: The Sleep of the Fasting Person Is Worship

Question:
May Allah reward you, Honorable Shaykh. What is the authenticity of the hadith: "The sleep of the fasting person is worship"?

Answer:
As far as I know, this is not a hadith, but rather the words of some of the Salaf (the earliest generations). It means that if one intends by his sleep to strengthen himself for worship, such as sleeping during the night in order to stand in prayer in the last part of the night, or sleeping during the midday nap in order to strengthen himself for standing in night prayer and the tarawih (the Ramadan night prayer), then this is worship because he intends it to strengthen himself for the obedience of Allah (Mighty and Majestic). As for sleep that one intends for laziness and by which he abandons the performance of acts of obedience, then this is blameworthy sleep, or it may be forbidden (haram) if it results in the loss of obligatory duties. Yes.
