The ruling on sleeping while being carried during tawaf and sa'y

Question:
He says: I carried my father on a chair during tawaf. When I finished the tawaf, my father said to me, “My son, I have been sleeping since the fourth lap.” The same was the case during sa’y on the same cart. What is the ruling regarding my father?

Answer:
As for sa’y, ritual purity is not a condition for it, and even if he slept, ritual purity is not a condition. However, he must be aware of the sa’y. If he was sleeping and was aware of the entire sa’y, he must repeat the tawaf and sa’y. But if it was just drowsiness, meaning he slept and then woke up, his sa’y is valid. As for ritual purity, it is not valid if he slept through the last four laps in a deep sleep. Drowsiness does not invalidate it. But if he was in a deep sleep where he was still conscious, this invalidates the ritual purity, so he must repeat the tawaf. If he was in a deep sleep during sa’y and was not aware of anything, he has no sa’y, because a worship act must be understood. Drowsiness, however, does not invalidate it. Yes.
