Narrated Abu Huraira (Radi-Allahu ‘anhu): The Prophet (Sallallahu ‘Alaihi Wa Sallam) said, “If anyone of you rouses from sleep and performs the ablution, he should wash his nose by putting
water in it and then blowing it out thrice, because Satan has stayed in the upper part of his nose all the night.”

Comments: Over the course of time, science is consistently proving the benefits of Islamic teachings. In this particular Hadith, our religion is recommending us to clean the nose in the morning. God knows what exactly are the inner benefits of this practice but regardless of these benefits our job is to ensure that we try to comply with the teachings of Islam as much as possible. This is to get barakah in our lives by obeying Allah’s commands.
