Sleep that invalidates the ablution
Machine translationRead the Arabic original
Question:
The questioner, Hissam, says: Shaykh, what are the limits of sleep that invalidate the wudu, and does drowsiness invalidate the wudu?
Answer:
The sleep that invalidates the wudu is deep sleep, whether one is leaning on something or lying down; this is what invalidates the wudu. As for the sleep of a person who is sitting and in control of himself, which is merely drowsiness, this does not harm and does not invalidate the wudu. This is because the Companions of the Messenger of Allah (peace and blessings be upon him) used to wait for the prayer with the Messenger (peace and blessings be upon him) until their heads would nod from drowsiness, and then they would stand up and pray. Yes.
