احسن الله إليك If I want to take a nap (1 or 2 hours) then should I say the adhkar which is legislated before sleeping?

From Shaykh Ibn ʿUthaymīn’s "Open Meetings": “What appears to me is that the prescribed bedtime remembrances (adhkār) are specific to nighttime sleep. However, there is no harm if a person says them before sleeping during the day, because they are general remembrances. There is no explicit text indicating that the Messenger (peace and blessings be upon him) would recite them exclusively before nighttime sleep.”
