The Sahabah (may Allah be pleased with them) learned the Sunnah of the Prophet (blessings and peace of Allah be upon him) and taught it to the Tabi‘in, so that the rulings of religion would become deeply rooted in a correct manner and would be handed down from one generation to the next. In this hadith, the Tabi‘i Yahya al-Mazini narrates that a man came to ‘Abdullah ibn Zayd al-Ansari (may Allah be pleased with him) and asked him: Can you show me how the Messenger of Allah (blessings and peace of Allah be upon him) did wudu’, and he said yes. Then he called for water, and when it was brought to him, he poured some water from the vessel onto his hands and washed them before starting to do wudu’. Then he cleaned his mouth by moving the water around in it, in order to wash it thoroughly. Then he spat the water out of his mouth, and sniffed up water into his nose to make it reach the highest part of the nose, and then blew it out of his nose, to cleanse his nose of any dirt that might be inside it. He cleaned his mouth and nose from one handful of water, and he did that three times. Then he washed his hands and forearms up to the elbows, twice each, washing each of them twice in order to show the easier way and to highlight the fact that it is permissible to do that. Washing the forearms cannot be done except after washing the face, but he did not mention it here, although he mentioned it in another report in al-Bukhari, which says that he washed his face three times. It was said that perhaps he wanted to make the description brief here, because the issue of washing the face is clearly mentioned in the verse of wudu’, and there is no need to mention it here. It was also said that perhaps one of the narrators forgot to mention washing the face, as he was also not sure about whether he washed or rinsed his mouth. It was also suggested that the reason why the face was not mentioned is that it may be that what is omitted is the word face; in other words, then he washed his face. It was omitted because it is clear [from the context], and the word aw (or) in the phrase “or rinsed his mouth” means “and”, and the phrase “from one handful of water” refers to rinsing the mouth and nose only. Then he wiped his head, placing his hands on the front of his head, then bringing them to the back of his head, until he reached the nape of his neck, then bringing them back to the front of his head again. He did that once, and wiping is less than washing. What is meant by the head here is the place where the hair grows. And he washed his feet up to the ankles. Then ‘Abdullah ibn Zayd (may Allah be pleased with him) said, after he had finished his wudu’: This is how the Messenger of Allah (blessings and peace of Allah be upon him) did wudu’. In other words, his wudu’ was a precise imitation of the wudu’ of the Prophet (blessings and peace of Allah be upon him), and it was done to teach those around him of the Tabi‘in and others who wanted to learn the Sunnah of the Messenger of Allah (blessings and peace of Allah be upon him). This hadith highlights how the Prophet (blessings and peace of Allah be upon him) did wudu’ in a practical manner. It also indicates that one should wash the hands before putting them in the vessel when starting to do wudu’..
