Question:
What is the ruling on one who sleeps lightly during the Friday sermon? Does his ritual purity become invalid?
Answer:
No, light sleep while sitting does not harm ritual purity. This is drowsiness, and drowsiness does not invalidate wudu'. The Companions (may Allah be pleased with them) used to wait for the Prophet (peace and blessings be upon him) for the 'Isha' prayer until their heads would nod, meaning they would doze off, and then they would stand up and pray without performing wudu'. Light drowsiness while sitting does not harm.
