"I saw the Messenger of Allah performing ablution and he wiped his head once."
Sunan Ibn Majah Book 1, Hadith 169
← Previous Hadith "Can you show me how the Messenger of Allah used to perform ablution?" 'Abdullah bin Zaid said: "Yes," So he called for water, poured it over his hands and washed his hands twice. Then he raised his mouth and sniffed water up into his nostrils three times. Then he washed his face three times and his arms up to his elbows twice. Then he wiped his head with his hands, from front to back. He started at the front of his head, then went with them to the nape of his neck, then he brought them back, returning them to the place he started, then he washed his feet."
