The obligatory extent of wiping the head
Machine translationRead the Arabic original
Question:
It was not obligatory on the head itself, and you did not act upon it, you were informed of their matters.
Answer:
The obligatory limit, as it came in the hadith, is that he wipes his entire head once, moving forward with his hands and backward, or backward and forward, so that he covers the entire head with the wiping. This is the wiping that suffices and the wiping that conforms to the evidence. If he did not wipe his head at all, his wudu' would not be valid according to the consensus of all scholars. As for if he wiped part of his head, this is a point of disagreement among scholars, and the stronger position is that it is necessary to cover the entire head, as has passed to you.
