The Messenger of Allah ﷺ said, "When one of you performs wudu, let him draw water up into his nostrils and then blow it out."
وقال رسول الله ﷺ إذا توضأ أحدكم فليستنشق بمنخريه من الماء ثم لينثر
This hadith is sahih, like the preceding ones, and it is in the Sahifa Mufradah, number 81. Muslim narrated it [1:146 S / 1:83 Bulaq] through the route of the Sahifa, but Bukhari did not narrate it through that route. He narrated it with similar wording through the route of the Aarraj manuscript, 1:229-230, Fath, along with the previous hadith, 8167. Its meaning has come up repeatedly before, including at 7298 and 7732, and see also 8063.As for his statement, "then let him blow his nose," this is what is established in the source manuscripts of the Musnad and Jami al-Masanid. In the Sahifa Mufradah it reads, "then let him blow his nose," which agrees with the narration of Muslim.
