Is it permissible to wipe over part of the head and suffice with the water remaining on the hand after pouring out the scoop, without this being a pursuit of dispensations? And is this method correct?

The opinion that it is permissible to wipe only part of the head is a strong one, and there is no harm for someone who acts upon it, even though wiping the entire head is more cautious. Wiping the entire head does not take a long time, and the sunnah method is to place the wet hands on the front of the head, then move them to the nape, then return them to the front, as the Prophet, peace and blessings be upon him, did. Some scholars have favored that it is not recommended to wipe the braids that hang down from the head.
