Yahya related to me from Ibn Shihab from Abu Idris al-Khawlani from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "The person doing wudu should snuff water up his nose and blow it out again."
Muwatta Malik Book 2, Hadith 3
← Previous Hadith Yahya related to me from Malik from Abu'zZinad from al-Araj from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "When you do wudu, snuff water into your nose and blow it out, and if you use stones to clean your private parts use an odd number."
