Ye must not say your prayers at the rising or the setting of the sun: so when a limb of the sun appeareth, leave your prayers until her whole orb is up: and when the sun beginneth to set, quit your prayers until the whole orb hath disappeared; for, verily she riseth between the two horns of the Devil.
No neglect of duty is imputable during sleep; for neglect can only take place when one is awake: therefore, when any of you forget your prayers, say them when ye recollect.
When any one of you goeth to sleep, the Devil tieth three knots upon his neck; and saith over every knot, “The night is long, sleep.” Therefore, if a servant awake and remember God, it openeth one knot, and if he perform the ablution, it openeth another; and if he say prayers it openeth the other; and he riseth in the morning in gladness and purity:—otherwise he riseth in a lethargic state.
When a Muslim performeth the ablution, it washeth from his face those faults which he may have cast his eyes upon; and when he washeth his hands, it removeth the faults they may have committed, and when he washeth his feet, it dispelleth the faults towards which they may have carried him: so that he will rise up in purity from the place of ablution.
