Abdullah bin Zayd Mazni · The Book on Purification

"1 saw the Prophet rinse his mouth and sniff water in his nose using one hand, he did that thrice,"

"Allah's Messenger wiped over his head with his hands, going over the front with them and the rear. He began with the front of his head until they went to the nape of his neck. Then he brought them back again to the place where he began. Then he washed his feet."

he saw the Prophet performing Wudu, and that he wiped his head with water that was not left over from his hands.

"The Prophet performed Wudu. So he washed his face three times, and washed his hands two times each, and wiped his head, and washed his feet ."
